the Internet Archive launched a new service that brings free access to more than 1 million books — from classic 19th century fiction and current novels to technical guides and research materials — now available in the specially designed format to support those who are blind, dyslexic or are otherwise visually impaired.
More specifically, through its Open Library interface, the Internet Archive has released many of its e-books in DAISY format. DAISY format is a preferred format for many people who don't use print, and this is a real improvement over the frequent that is "but I put up a PDF so it's accessible" (frequently an untagged, inaccessible PDF). Thank you, Open Library.
