Books for people who don't read print?

The Internet Archive is proud to be distributing over 1 million books free in a format called DAISY, designed for those of us who find it challenging to use regular printed media.

There are two types of DAISYs on Open Library: open and protected. Open DAISYs can be read by anyone in the world on many different devices. Protected DAISYs (like this one) can only be opened using a key issued by the Library of Congress NLS program.



What is the DAISY format?

The DAISY digital format helps people who have challenges using regular printed media. DAISY digital talking books offer the benefits of regular audiobooks, with navigation within the book, to chapters or specific pages.
