Consider the source
Posted by Teresa at 12:30 PM *

A number of news venues and weblogs (notably Electrolite, which picked it up from Arthur Silber) have commented on the recent AP story about how the FBI is urging the police to watch out for people carrying almanacs:

The FBI is warning police nationwide to be alert for people carrying almanacs, cautioning that the popular reference books covering everything from abbreviations to weather trends could be used for terrorist planning.

In a bulletin sent Christmas Eve to about 18,000 police organizations, the FBI said terrorists may use almanacs “to assist with target selection and pre-operational planning.” It urged officers to watch during searches, traffic stops and other investigations for anyone carrying almanacs, especially if the books are annotated in suspicious ways.

“The practice of researching potential targets is consistent with known methods of al-Qaida and other terrorist organizations that seek to maximize the likelihood of operational success through careful planning,” the FBI wrote.

The Associated Press obtained a copy of the bulletin this week and verified its authenticity.

“For local law enforcement, it’s just to help give them one more piece of information to raise their suspicions,” said David Heyman, a terrorism expert for the Washington-based Center for Strategic and International Studies. “It helps make sure one more bad guy doesn’t get away from a traffic stop, maybe gives police a little bit more reason to follow up on this.”

The FBI noted that use of almanacs or maps may be innocent, “the product of legitimate recreational or commercial activities.” But it warned that when combined with suspicious behavior — such as apparent surveillance — a person with an almanac “may point to possible terrorist planning.”

“I don’t think anyone would consider us a harmful entity,” said Kevin Seabrooke, senior editor of The World Almanac. He said the reference book includes about a dozen pages out of its 1,000 pages total listing the world’s tallest buildings and bridges but includes no diagrams or architectural schematics. “It’s stuff that’s widely available on the Internet,” he said.

The publisher for The Old Farmers Almanac said Monday terrorists would probably find statistical reference books more useful than the collections of Americana in his famous publication of weather predictions and witticisms.

“While we doubt that our editorial content would be of particular interest to people who would wish to do us harm, we will certainly cooperate to the fullest with national authorities at any level they deem appropriate,” publisher John Pierce said.

The FBI said information typically found in almanacs that could be useful for terrorists includes profiles of cities and states and information about waterways, bridges, dams, reservoirs, tunnels, buildings and landmarks. It said this information is often accompanied by photographs and maps.

The FBI urged police to report such discoveries to the local U.S. Joint Terrorism Task Force.
The first thing that struck me about that story was a sense of the familiar made strange. I know Kevin Seabrooke. Yon purveyor of information to terrorists used to work in Ad Promo at Tor, during which time Editorial’s nickname for him was “Captain America”. Next to Kevin, Norman Rockwell paintings look faintly debauched. It’s truly weird to run across him in the context of a nationwide FBI alert. On the other hand, it means there’s at least one quote in the story I can believe without question—not that I’d have thought anything else of the World Almanac.

That aside, this is just a phenomenally dumb move. The old hardcover family almanacs might or might not have gotten annotated, but your modern year-by-year trade paperback almanacs certainly do. If someone’s carrying an almanac around with them, there’s a good chance they’ll have jotted down notes in it. Who’s this going to catch? Schoolteachers. People with children. The more earnest sort of traveler. The last person I saw annotating an almanac in public was a nice woman who turned out to be a professional tour guide. One of her routes covers various sites and sights in my Brooklyn neighborhood. She was annotating her book because she’d just been out checking her route for changes.

What scares me, though, is how specifically the FBI has targeted almanacs, and how they haven’t mentioned travel guidebooks, high-resolution terrain maps, architectural guides, government directories, maps of underground water, power, and transit systems, lists of major industrial sites, the Yellow Pages for pete’s sake, or any of the other references that might reasonably be used at that stage.

I’m not just alarmed because this lets hypothetical terrorists escape scrutiny by taking their notes in a travel guide instead of an almanac. If you want to see how someone does research, look at how they imagine someone else doing it. If the almanac is the only documentation that comes to the FBI’s collective mind when they visualize potential terrorists engaged in “target selection and pre-operational planning,” what that suggests is that almanacs are pretty much what they’re working from when they’re doing their own target selection and pre-operational planning.

That’s unsettling. Almanacs are a great resource, a good place to start your research, but they’re the very definition of “general information.” Somehow, I feel as though I’d just found out that FBI agents were all recruited from the kids who did their class reports by copying stuff out of the encyclopedia.

One would hope that some of these at least were on a previous list that wasn't leaked. Or that they are already a specific part of FBI training. Because if the FBI doesn't know to look twice at someone toting maps of power and transit systems, then we've got really big problems.

My mind must not work the way all of yours do: the first thing I thought of was that they'd been tracking book purchases and found a lot of almanacs going to names on lists, or to places where they think terrorists are training. I'm more appalled at the idea they keep track of book purchases (and yes, I know they've been doing it and that good bookstores refuse to let them look at the records) than by the portrayal of agents as so uncreative as to focus on almanacs.

One data source widely used in my field (natural language processing and information retrieval) is the CIA world factbook, which has most of the characteristics of an almanac. Another source, used when you want to build something like an address recognizer is the FIPS55 data, which the US government distrbutes for free through the National Institute of Standards and Technology. I wonder if they will start tracking people who download them in future; or perhaps they already are.

If terrorists were really into reference books, they'd use Chase's Annual Events. It tells what special events are going on, at least in the U.S., every day of the year, as well as a good bit of the stuff that's in almanacs. (It doesn't tell things like the tallest buildings, largest bridges, etc., though, which may be what the FBI thinks terrorists are really wanting to know.) We use it a lot at our reference desk. But I still love the World Almanac best even if I need stronger glasses to read it these days. Their print is getting awfully small lately! :-)

I've been known to tell people my motto is, "The World Almanac -- don't leave home without it." As I mentioned over on Electrolite, I may start taking that literally, just for spite.

#20 ::: julia ::: (view all by) ::: December 30, 2003, 08:00 PM:

The problem with this is that now, finding an almanac on someone they're interested in taking a closer look at is probably probable cause to search everyone in the car/house with them.

Not that they need probable cause these days, but it's rather disconcerting, and I say this as a domesticated-looking middle-aged white woman with blue eyes and freckles who regularly goes by checkpoints unchecked (my party was actually waved through at the Canadian border, and they never asked to look at my ID at LAX).

I have to agree with Julia. It sounds like they're developing grounds for reasonable cause so they can get to someone in particular. Unfortunately, such actions almost always hit someone innocent as well.

Then too, I wonder what over zealous police officers would make of my possessing a little handbook containing information on internation countries, cities, money exchange rates, methods of measurement. I carry it around in one of my backpacks....and I'm kinda curious if "I have this for Trivia Night" would go over well as an excuse.

One wonders what the FBI would think if they considered that, right now, there are probably Arabs in the US poring over books on cryptography, power transmission lines, bridge construction, and other things.

They're called 'college students', of course. But I can easily imagine the FBI using a required textbook as evidence of evil intent.

Charlie: Almanacs are general reference books which have things like lists of award winners, tall buildings, statistical info, dates for rising and setting of the sun and sometimes the moon and other planets. The Old Farmers Almanack lists weather forecasts and times to plant. Reference librarians use almanacs, dictionaries, and encyclopedias more than any other book.

Charlie, what Mary Kay said. Back when many rural American households only had two or three books, one was almost certain to be the Bible, but it was a good bet that one of the others was an almanac. The climax species almanacs were vast compendious things containing weather forecasts, gardening tips, tide charts, historic dates, lunar calendars, weights and measures, postal rates, the text of the Constitution and other basic documents, home remedies, collected proverbs and wise sayings, distances between major cities, and sixty-zillion other things.

Their descendants are longer on records and statistics, and not as focused on planting times and proverbs, but they're still vast compendious something-of-everything general reference books.

John Tukey, one of the great statisticians of the last century and the developer of exploratory data analysis and fast Fourier transforms, collected World Almanacs. I made him very happy by finding half a dozen years he didn't have when we were at the AAAS meetings in Detroit.

He was very interested in how the information for previous years changed from one year to the next. In the almanac world, revisionist history is apparently a requirement -- and the changes are generally not marked, and not obvious.

I wonder what happened to his collection?

#32 ::: Avram ::: (view all by) ::: December 30, 2003, 11:38 PM:

Merriam-Webster suggests that almanac may be derived from the Arabic al-manAkh. Maybe that92s why it92s just almanacs. Presumably the FBI92d be even more suspicious if they were to find you working out algebra in your almanac, especially while while drinking alcohol from a carafe and eating apricots.

If the FBI cites almanacs because a suspected terrorist was found with an almanac, then this is just another example of fighting the last war, without any realization that the next terrorist might think of something else. Our security forces seem to think of terrorists as natural phenomena with predictable patterns, like hurricanes.

I believe it was someone on this weblog who once wrote, "Every time I take my shoes off at airport security, I give thanks that Richard Reid wasn't known as the underwear bomber."

Emma wrote,

I hope you don't think this is just an imaginary scenario, or something that might happen in the future. Something very like this call was made about me quite recently. And I don't even look that much like an Arab. I don't want to describe the incident, except to cite this mitigating factor: that the cop who questioned me seemed deeply embarrassed by the whole thing, and let me go with no fuss.

If using words derived from Arabic is in itself suspicious, then I have to cast a baleful glance towards the institutions of Homeland Security themselves, which currently have us on orange alert.

I tend to use my almanac to find such sensitive information as zip codes and election returns, so I'm skeptical of the great threat it poses. On the other hand, were I ever to plan a Topkapi-style cat burglary of a major European museum, the first thing I'd want would be a Dorling-Kindersley Eyewitness Travel Guide. I commonly refer to it as the "Junior Woodchuck Manual."

On the other hand, weren't the anthrax letters of late 2001 were tied together because the return address had an incorrect zip code?

If I ever wanted to find my way to the exit of a major European museum, the first thing I'd want would be one of those D-K guides. Those places are really easy to get lost in, and the D-K guides are really fab.

And now I have to worry about being considered a terrorist for using one. Great.

Xopher, I have no idea about the particular thing James is talking about, but I would guess that he's thinking of some method (every nth letter? All the population data about the countries in Asia?) of turning the information in an almanac into something approximating a one-time pad. If given an almanac and told I had to use it to encode a message, that's what I would do. (Although if that's it, the almanac-ness is only useful in that there's a lot of data in the book.)

It is indeed using the almanac as a one-time pad, with the plaintext changed to ciphertext using a straddling checkerboard.

It'd take too long to explain, but only a couple of minutes to demonstrate.

I remember reading about the almanac cipher. You and a friend both have access to identical books, and he can send you a coded message of just numbers that are meaningless to anybody who doesn't have the almanac. Suppose the first number is 315002015. You turn to page 315, paragraph 2, 15th word, and you'll see where someone has written in: "We blow up the dam at midnight. Bring lots of dynamite."

Ah, with such a cipher, I could -- dare I say it? -- Rule the World!!

#50 ::: Charlie Stross ::: (view all by) ::: December 31, 2003, 01:34 PM:

Alan: a world where "computers fit in bookbags and backpacks and where ports of PGP are available for PalmOS" is also a world where there's an FBI-owned DCS2000 sniffer sitting on every ISP's backbone, and if you think PGP is safe you haven't been following the news about developments in quantum computing.

In contrast, pencil-and-paper one-time pads, dead letter drops at Greyhound bus stations, and plain old-fashioned cell structures with minimal information flow offer security no worse than they ever did -- and the opposition (read: the FBI, DHS, NSA, and so on) have stopped paying attention to anything as old-fashioned and low-budget as HUMINT resources.

If I was setting up a terrorist network today, rule #1 would be "no technology invented after 1970 shall be used for secret communications". It's amazing how efficiently sticking to that rule defeats most current-day surveillance measures.

The only problem Kip (as I suspect you already know) is that book ciphers are secure only in special situations. (See this for some background.) The problem is that if you manage to get a crib, there are ways to reconstruct the keytext, even if you don't have the code book. As Charlie just mentioned, better to use one time pads.

Dennis -

My friend, an archivist, recently returned from a conference in Canada. When she went through U.S. Customs at the (Vancouver) airport, they asked what her profession was. When she answered "I'm an Archivist." the customs agent responded with an alarmed look and was about to call another agent or security guy over when she calmly explained to him the nature of her job.

Her colleague, driving back from another Canadian project in a rented car, had a similar (but somewhat scarier) experience the previous month: He must have chuckled when the border agent wigged out about the "Archivist", and the border guys took umbrage and searched his car. The found about 42 euros in a plastic bag hidden in the wheel well of the rental car. This really pissed them off, and they did a greater search, asking if there was anything in the trunk he should tell them about. He responded (somewhat less shirtily in this case) that he hadn't known about the 42 euros, since it was a rental.

These incidences have left me with two life-lessons:

1) Don't. Ever. Smile. when going through customs or crossing a border. This is especially important to Librarians and Archivists, as the ones I've know tend to have a keen sense of both sarcasm and the absurd.

2) People are getting dumber and more paranoid. I suppose not everyone has a brain that hears an unfamiliar word and thinks: "Hmmm... archivist... from the greek..." but use your head, dammit! Is "Anarchist" (what I'm sure was their brain's neuron-jerk reaction to the unfamiliar word) really a viable Profession? That they would be having a Professional Conference? Anarchy doesn't really make one think of careful planning and name tags.

The real advantage of semi-exotic ciphers (almanacs, Silmarillions, decks of cards) is that, while not as secure as true one-time pads, they offer a substantial number of pseudo-one time pads and are both easily concealed and obscure (security through obscurity is not reliable, but if you're a gambling man, its worth a try.)

(If my backpack contains an almanac, a notebook containing ciphertext, and little else, you're still going to need time and human ingenuity to figure out what the agreed-upon method is -- if you've never heard of the almanac cipher, or if I'm carrying five different almanacs, three decks of cards, a copy of the classfied section of three major newspapers, and the complete works of Tolkien, I've stymied you barring interrogation.

I don't think we have almanacs in the UK anymore.

Okay, here's complete workshop instructions on how to use a straddling checkerboard with an almanac or phonebook to create a pretty decent pencil-and-paper cipher. The straddling checkerboard was used by the Jesuits in the 16th c., while the combination of the straddling checkerboard and the tabular numerical data was used by Die Rote Kapelle during WWII, transmitting Nazi military information from Berlin to Moscow.

Here's how to work it.

First, make up your straddling checkerboard.

..3456789012
.|etaonris
1|bcdfghjklm
2|pquvwxyz/.

With this cipher you have the most frequent letters in the top row, which has no number to its left. Any letter found in this row will only have one number associated with it. Numbers from the next two rows are designated with two numbers, the first of which is always a 1 or a 2. (Note: you can arrange the numbers any way you please, and changing them (and the exact letters in the grid) daily is a good idea).

So: To make FRED IS HERE into cipher text:

16 8 3 15 9 0 18 3 8 3

16831 59018 38371

(In five-character groups, with nulls added to fill up the final group.)

When decrypting, go through and find every 1 or 2. Circle it and the number that follows it. Those will be your letters that are formed from two-numeral coordinates. Any number not preceded by a 1 or 2 is one of the top-row letters. (Advantages of this cipher include the fact that unlike normal checkerboards, the length of the message isn't doubled. Another advantage is that sometimes a numeral contains all the information about what the plaintext letter it represents is, sometimes it only contains half the information.)

So you have your ciphertext. Now you take a large set of random numbers (your one-time pad, your almanac, your phone book) and add them to the ciphertext using non-carrying addition.

16831 59018 38371 Ciphertext.
13446 27022 58334 56034... key.

29277 76030 86605 Final Ciphertext.

Now, we need to tell our correspondent where the key starts. So: Pretend that I have a pair of agent numbers, and they're 18181 and 46979 (the bad guys will only find these out by finding me, then using drugs, money, or rubber hoses to learn it). This key is from a phone book. I start on a certain page, in this case 093 with entry number of 87 (the 87th listing on the page, starting at top left). I'm using only the last four digits of each phone number I come to, skipping boxed display ads.

I add my numbers to the page and line numbers, to the day, month, and year:

18181 46979 Agent numbers
09387 09387 Page and line
31123 31123 Date

48581 76389 Keyblocks

These are inserted in the message in prearranged places (for the example, I'll use second from the start and second from the end):

29277 48581 76030 76389 86605 Cipher As transmitted.

Now, we have a couple of special characters in the grid: . and / . is the period, the full stop. Used to end sentences. / is the letter/mumber shift. When you have to send numbers, you put in the shift symbol, then place each digit thrice. When you shift back to letters, you do a shift symbol again. Thus:

CONTACT FRED ON 103.67 KHZ would be rendered

CONTACT FRED ON /111000333/./666777/ KHZ

14674 51441 68315 67211 11000 33321 22216 66777 10182 01327 (with nulls).

Key (begins page 129 line 12):

3127 6647 3611 3692 5045 3416 3814 4603 6560 3519 3128 3599 2213

Keyblocks

18181 46979
12912 12912
31123 31123

51116 89904

Finished text:

45840 51116 15177 79674 82256 45138 37781 58776 91860 22917 89904 90548

A few more notes:

Carry everything (except the almanac or phone book or what-may-have-you) in your head. Only reconstruct the keys (from memory) when you are actually enciphering or deciphering.

When you're working, use single sheets of paper (don't put one sheet on top of another, don't use a pad of paper). Put the key on one sheet, the plaintext on a second sheet, and the ciphertext on a third sheet. Plaintext, key, and ciphertext are never to be on the same sheet of paper. Never!

Immediately after you finish ciphering, burn the plaintext and ciphertext sheets. Stir the ashes.

Avoid electronic communications whenever possible.

Assume that the method you're using is known, and that the only thing protecting your information is the key. Assume at least one member of your group is a spy. Everything goes strictly on a need-to-know basis.

If a member of your group is captured, change all your keys immediately.

#60 ::: Dave Kuzminski ::: (view all by) ::: December 31, 2003, 08:17 PM:

My system is simpler. Create a group of equations. A group of ten will be enough. One equation might be X+Y=result. Another might be X times Y= result. What is important is that each of the equations in the group must result in a two digit number or each must result in a three-digit result. The sample equations I used here as an example are not real. Those require a little work to prepare properly, but those are actually quite easy for anyone who graduated high school algebra with at least a C grade.

X will be the character that you want encrypted. Y will come from the key phrase. The key phrase can be a password sentence you construct or it can come from some other source provided you have a secure means of transferring the key phrase separately.

At this point, substitute a value for each character in the key phrase. You can keep it simple by using the ASCII values since I designed it originally using a computer. Consequently, if the key value is a sentence of forty characters, then you will use the group of equations four times before you return to the beginning of the key. If you're encrypting the letter B and your first key value is an A, you would substitute the ASCII value for B in the X position of your equation and the ASCII value for A in the Y position of your equation. Do the calculation with those values. Record the result. Now do the second letter of the message. Assuming that it's an E, you would substitute the ASCII value for E in the X position of the second equation and the ASCII value of the second character from your key phrase in the Y position. You would then calculate the results of that equation and record the result. If the next character is a space, do the same thing. Substitute the ASCII value for a space in the X position of the third equation and substitute the ASCII value from the third position of the key phrase into the Y position and calculate and record the results. When you reach the end of your group of equations, restart with the first equation. The same thing happens with the key phrase. When you reach the end of it, go back to the beginning of the key phrase. If one of the two is an odd amount, that will strengthen the results because it will make different values appear in the same equations for Y which means that even if the letter A should be encrypted twice within the same message by the first equation, the calculated result stands a better chance of being different. Likewise, this takes care of repeated letters such as in MOON where there are two Os. Since each O would be calculated by a different equation, the results will probably be different. This strength can also cause two different letters to appear to be a repeated letter when different equations come up with identical results. Because the results from every equation is either a double-digit or triple-digit number, there's no need to wonder where the code separates. However, since the numbers are listed sequentially without any breaks, it presents no clue as to which kind of result was created. When the recipient receives the code, he already has the key. He now has the results. He plugs the values into a reverse set of equations and out comes the clear text.

YES, there are some other stipulations that I'm not listing such as how does the recipient know which key phrase to use if he has a list? Or, how does he know whether to break the results into two-digit or three-digit groupings (which could vary from recipient to recipient)? All I'm giving are some of the basics for creating a very strong code that does not create patterns because even the spaces and punctuation are coded and everything is run together as a single very long integer. Yes, I created a computer program that used this technique and it worked very well for both encryption and decryption.

Dave Kuzminski:

doesn't it matter that not all such equations give equally distributed probabilities of various 2-digit and 3-digit combinations?

Thus, the output at each step does not have the Zipf's Law kind of power law distribution of about 30% of 2-digit and 3-digit combinations starting with "1" and so forth?

Isn't failure to have pseudorandom distributions a guarantee that there is still some structure for cryptographers to chew on?

Sorry, it's a LONG time since I did the Finite Field math and Galois Theory used in crypto, as well as being one of the very first to code Public Key Cryptography on a PC (namely a Processor Technology Sol-20 in 1976, as I demo'd with Ted Nelson and Mark Miller at the world's First Personal Computer Conference, in Philadelphia).

All I knew was that patterns were highly instrumental in breaking codes (learned that from WWII movies) and that any code worth its while would deal with that problem. Nice to know I didn't invent something new so that I shouldn't expect the nice government men to show up and escort me to a special house.

Just did an Internet search and found a site with an excellent description of that method. You're right. Mine is almost identical. My method just uses math to derive a table like that method used and I go just a bit farther in applying it to all punctuation, including spaces, though I can see that wouldn't make much difference to anyone trying to break the code. It would still create some repetitions if the key phrase is short enough. My program allowed a key phrase up to 255 characters long. That might have made a small difference, but I doubt if it would really be significant in the long run.

What might be of interest in this context is Between Silk and Cyanide, subtitled A Codemaker's War, 1941-1945, by Leo Marks. Mr. Marks worked for MI8 during WW2, as a cryptographer, and faced a number of practical problems with regard to basic communications between agents and HQ. The title of the book refers to an interview he had with a government person wherein he convinced that person that reams of silk, in extremely short supply and absolutely necessary for parachutes, should be allocated to his department as the material on which cyphers were printed. The argument he put forth was that either they use silk, or they continue to have a large proportion of agents suiciding due to being compromised.

He writes well-- it's a real page-turner-- about the various methods they used to ensure security of their communications, and a key factor in all was imagination. The foundation of their system was "poem-codes", where the agents memorized not just standard poetry, but also composed their own. Everyone in the office was writing poetry, to provide fodder for the encryptions.

They made use of one-time pads as well, but it appears from this account that those were difficult to implement over an on-going series of communications, where an agent is in place over several weeks or months, and expected to make regular reports. Using a one-time pad system would mean talking back to the agent, in order to set up each translation, and such contacts from HQ tended over time to compromise the agent.

The beauty of the poem-code system lay in its unpredictibility. English is a language peculiarly suited to writing doggerel, which lends itself to being memorized by a native speaker, but which is so much noise to the non-native speaker. So the agents could write and memorize yards of this stuff, not found in any standard reference or publication, and use it to create encrypted reports. The home office, having a copy of the doggerel on file, would then be able to decrypt it in a reasonable space of time.

Kayjay, you're not missing anything. The silk was important because poem-code has its drawbacks and Marks was among those working to institute an alternative, a more secure one. Its drawback as well as its strength was that it could not be memorized, so the agents would have to go into the field with part of the codes written down on something. Marks wanted to use silk since, "Silk itself was easy to cut, easy to burn and easy to camouflage. If the Gestapo or Vichy police ran their hands over an agent's clothing during a random street search, silk sewn into the lining could not be detected."

What took the FBI so long?

Consider the following from page 2 of The Washington Post:

FBI spokesman Ed Cogswell said the bulletin was meant to provide general information to local police and was not the result of a specific threat. It does not refer to any specific cases involving almanacs. But investigators have said that during a search of the apartment of alleged al Qaeda sleeper agent Ali Saleh Kahlah al-Marri, they found an almanac with bookmarked pages on major U.S. dams, rivers, reservoirs and railroads.

A quick web search will tell you that al-Marri was arrested in "late 2001." One can presume his apartment was searched at the time. Why do you suppose it took 2 years to pass this vital information on to the rest of the law enforcement community?

Otherwise not much to add to TNH's excellent commentary. It's nice to see such a strong world-wide reaction to this story.

There was one year that I took a highlighter pen to my World Almanac -- my home copy, not the library's -- and marked all the rivers, bridges, tall buildings, etc., that are in this tri-state area (western Pennsylvania, West Virginia, and eastern Ohio) or that I'd been to. Didn't mean anything by it except curiosity and local pride. For instance, we seem to have in our area at least one of almost every kind of bridge there is except drawbridges.

When I heard about this bulletin, that's what came to mind. But that's the glory of lists of raw facts like that -- something for everyone, and different people can make or unmake of it as they will.

The FBI would have fun with my almanacs. I also have been known to mark such things as World Series, Super Bowls, and Stanley Cups won by the local pro sports teams, dates of Easter (both western and Orthodox), solstices and equinoxes, birthdays of some of my favorite celebrities (or celebrities with the good taste to have the same birthday as I do), the formula for "correcting" rise/set times for our area, and the perpetual calendar, which is one of the pages I use most. Not sure what use it would be, even in an FBI agent's most feverish imagination, for a terrorist to know that the Pirates won the 1960 World Series, but it's one of my favorite memories.

In 1942 a German spy was apprehended by the FBI after being landed on Long Island, New York, by a U-boat the night before. The impact of this event was felt all the way to Dublin, New Hampshire, because The Old Farmer's Almanac was found in his coat pocket. The U.S. government speculated that the Germans were using the Almanac for weather forecasts, which meant that the book was indirectly supplying information to the enemy.

Fortunately, Sagendorph managed to get the government to agree that there would be no violation of the "Code of Wartime Practices for the American Press" if the Almanac featured weather indications rather than forecasts. It was a close call that almost ruined the Almanac's perfect record of continuous publication.

For example, if every Librarian who goes through customs states that they're a tourist, do the remaining Librarians who don't know the "code" seem even more exotic (read: dangerous) by their rarity?

Although I don't have any head at all for numbers, I am fascinated by cryptography. My husband and I both enjoyed "The Code Book" by Simon Singh, which covers codes from Greek and Roman times to quantum cryptography, and even had a picture of an Enigma machine. (I read the description in Cryptonomicon several times, but it made no sense to me, but seeing the picture helped.)

Upon finishing the book my husband commented that in the future when he captures enemies, he'll make sure to shave their heads, to search for secret messages.

I'm a little concerned about the terrorist...er..."tour guide" that you mention in our post, Teresa. Sleeper cells of Islamicists may very well be giving tours of the famous mob hits in Little Italy while planning something very, very, evil and almanacish.

Oh dear. Just noticed the sad news about Leo Marks, who I remember hearing interviewed recently (last year?). Perhaps it was a repeated show.

I only managed to read Between Silk and Cyanide last month after being interested in it for some while. Had been impressed, given a copy to a friend, etc.
Was considering sending letter of appreciation. Looks like I'll have to write it, then burn it to send the message to The Other Side, according to some traditions, now.

At least it's the right day for burning such tributes.
