[Athen] Braille Textbooks

[Jeffrey Dell]

Hello
Before I send textbooks to a transcriber I look at some catalogs,
usually without success, to see if someone has already transcribed the
book. I look on the APH, National Braille Press, and the California
Community College Alt Text Production Center's catalogs.  Are there
other catalogs that I should be looking at?
We only have had math books transcribed so I don't do many searches
like that.  I'd appreciate any tips that you could give me.
