Assistive Technology for Researchers

To access our collections, the Library of Congress provides a network of reading rooms and research centers in three separate buildings on Capitol Hill as well as other satellite facilities. For researchers with disabilities, many types of accommodation equipment are available through our Assistive Technology Demonstration Center. Because our materials are increasingly available in multiple formats (e.g. manuscripts, surrogate service paper copies, and electronic versions), please contact us in advance to determine a match between your research plans and your accessibility needs.
