This is also a problem that arose in the Google Libraries project 
(http://newsbreaks.infotoday.com/nbreader.asp?ArticleID=16307), where 
the plan was to scan the library resources of Harvard, Stanford, the 
University of Michigan, and Oxford University, as well as the New York 
Public Library (NYPL) and make them available for online searching. I 
don't know what has happened recently, but the original plan was to show 
the search results in a tiff file (which, since it is an image file, is 
inaccessible to screen readers). John Wilkin at U Mich libraries had 
brought the need for accessibility to Google's attention.
