The viewer makes EPUBs available for reading on loc.gov and provides a richer interface for users. However, we recognized an increase in titles available in EPUB only so we are happy to share the news that an EPUB viewer was launched on loc.gov.

As many books were available in both formats or in PDF only, this ensured most titles were viewable directly on the website.

When we first made open access e-books available on loc.gov, titles were available for download in either PDF or EPUB format, but PDF was the only one available for reading directly on the website loc.gov did not support viewing EPUBs in the browser and they were only available for download. Bird Species: How They Arise, Modify and Vanish is now available to view in the new EPUB reader. Users can access the e-books in the Open Access Books Collection by reading directly online in a browser or downloading the book as a PDF or EPUB file. All books in this collection were published under open access licenses, meaning the e-books are available to use and reuse according to the terms of the licenses. The Open Access Books Collection on loc.gov includes approximately 6,000 contemporary open access e-books covering a wide range of subjects, including history, music, poetry, technology, and works of fiction. Today’s guest post is from Kristy Darby, a Digital Collections Specialist at the Library of Congress.
