ARL has released SPEC Kit 358: Accessibility and Universal Design .
Here's an excerpt:
This SPEC Kit explores how ARL member libraries are meeting the accessibility needs of individuals with disabilities. This study gathered information on support for assistive technologies in libraries, services provided to individuals with disabilities, staffing and training for these services, evaluation of resources, and institutional policies and procedures in this area. It also includes questions on universal design, an approach to design that makes spaces and services more inclusive of all, regardless of their needs.
