I believe you'll find some information on multilingual database
applications at
http://www.trigeminal.com. That is Michael Kaplan's
website, and he was, at one time, considered one of the foremost
specialists on multilingual applications in Access. His focus has now
changed and he isn't working as an Access consultant, currently, but he is
still very knowledgeable. I don't know if he wrote a book on the subject,
but you might search for one.
