Lindsey Simon writes: “In the 1930s, Congress established the Library of Congress’s National Library Service for the Blind and Print Disabled to provide free accessible reading materials to Americans with low vision. Over the years, the program has expanded to offer new technologies like refreshable braille displays, as well as broadening its eligibility requirements to include people who aren’t blind but have other disabilities that make it challenging to read print. Materials circulate through a network of regional libraries and outreach centers that serve all 50 states, the District of Columbia, Puerto Rico, the US Virgin Islands, and Guam.”
