I discussed accessible workstations for libraries in an article published in
"Information Technology and Disabilities" in 1995: THE AD-A-P-T-A-B-L-E
APPROACH: PLANNING ACCESSIBLE LIBRARIES.
(An almost identical article with a similar title appeared in "Library Hi
Tech News" the following year.)
The "Information Technology and Disabilities" article survives on the Web:

I just re-read the article, and except for a few details, the content still
seems relevant. (To me, anyways!)
