Knowledge of disability culture is important to library and information professionals/practitioners because the more one knows about and understands a particular group of people, the more one is able to help them access information. It is important for information professionals to learn about the groups that they serve broadly and on an individual basis.
Barriers can exist in library and other informational agencies for individuals with disabilities, such as a lack of accessible formats, a lack of accessible technology, a lack of understanding and awareness on the part of the staff, a lack of accessible building architecture and interior design layout space.
The more library and information science practitioners learn, know, and understand about disability culture and barriers, the more able they will be to start breaking down barriers and providing environments where information and resources are more accessible to everyone.
Some books I would like to read related to assistive technology include:
Blair, V. & Green, R. A. Keep It Simple: A Guide to Assistive Technology. Santa Barbara, CA: ABC-CLIO, LLC.
Robitaille, S. The Illustrated Guide to Assistive Technology & Devices. New York: Demos Medical Publishing, LLC.
Some websites with general assistive technology info:
Alliance for Technology Access website.
National Library Service for the Blind and Physically Handicapped website.
Rehab Tool website.
Technology Access and Assistive Technology, an overview from the Association of Specialized and Cooperative Library Association (ASCLA).
In closing, for library and information professionals and others, learning about accessibility is an ongoing process and an exciting topic to explore.
