Can American Librarian Conferences have more attendees with disability than other conferences? Maybe not, but they are addressing the issues. The American Library Association has discovered several problems such as inability to present, attend, and situations leading to outright embarrassments. This has led to research and a comprehensive document with 81 recommendations that cover before, during and after the event. Here is the abstract to the paper with other links.
