A talking book for the blind with no moving parts has been designed. It will read a volume digitally from a card smaller than a credit card and looks and feels like a book.

Buttons along the edges will enable the blind reader to turn pages forward and backward, skip quickly, insert bookmarks, and search for a remembered passage. The Library of Congress will convert about 30,000 titles, mostly standard works and best sellers, to the new technology at a cost of about $75 million.
