What's the date on the fourth edition? There are copies on ABE of the workbook starting under $10 for 1999 and 2002 editions. And the title appears to be Conexiones, not Oonexiones. Makes the search easier if one knows that.

In an alternate universe, there is a vogue for learning specialized vocabularies in foreign languages through intense conversations about a single topic. In Spanish, there is ¿Qué Gusto?, where the student learns Spanish by writing restaurant reviews, and there is Dos Mundos, where the student learns Spanish through writing travel-between-parallel-worlds SF.

And there is, of course, Oonexiones, wherein the student learns Spanish by providing free fertility counseling. Or possibly by working at an egg farm. I'm not quite sure.

Fixing the title (yes, it's Conexiones) and the date of the 4th edition is 2009.

We've found an on-line sales link for the 2009 edition. New, of course . . . not going to be many secondhand ones available this soon. Not that going secondhand is a particularly safe option, for a workbook&CD combo -- too many of the used workbooks available have answers written in, or pages missing, and most of them don't have the accompanying CD.

Have you tried Half.com?

It's pretty good for textbooks.

That seems to be the correct workbook.

Lighthill @2:

Don't forget VISTAS, the fad for teaching people Spanish by making them work tech support for Microsoft.

(I had to use that textbook. It's actually not bad, if unintentionally funny in all the usual ways, plus one of their Example Actors being American and sometimes having a very good Madrid accent, but sometimes sounding like an American).

Also, Collage, which teaches people French through mosaic, decoupage, and multimedia assemblage art.
