Abstract
There is an increasingly rich body of literature surrounding digital accessibility in libraries, ranging from practical guides for authors of web content, to principles of universal design, to the ethical considerations of libraries subscribing to packages of digital content, to critical examinations of the accessibility guidelines themselves. The goal of this paper is to review the library and information science (LIS) literature related to the accessibility of digital resources by individuals with mental, physical or other impairments, in order to assess the state of research in the field and to explore new avenues for investigation. This review is intended to be illustrative, not exhaustive; less attention is given to studies of specific tools that will become quickly outdated, and more is given to underlying considerations and approaches that will remain relevant even as technologies change. This review offers theoretical and practical perspectives from recent work that can assist librarians in planning and decision making as they deal with an increasingly complex landscape of digital resources.
