The eBook Store from Sony, together with Google, today announced it is providing access to more than 1 million free public domain books.

Sony's electronic readers digitize classic titles not protected by copyright using Google's Books project. The titles are available in EPUB format and are optimized for current models of the Sony Reader Digital Book.

From Sony?s eBook Store (ebookstore.sony.com), Reader owners with a U.S. location can download and transfer any of these titles to their PRS-505 or PRS-700 Reader. New eBook Store users can access available titles after setting up an account and downloading Sony?s free eBook Library software.

The Reader Digital Book?s high-resolution electronic paper display delivers a realistic print look and uses minimal power. A single battery charge provides up to 7,500 pages of continuous reading.

In addition to electronic books, the current Reader models support multiple file formats for personal documents and music. Users can transfer Adobe PDF documents with reflow capability, Microsoft Word documents, BBeB files and other text file formats to the Reader. The device can store and display EPUB files and work with Adobe Digital Editions software.

There are two Reader models available, including the PRS-505 (starting at approximately $280) and the PRS-700 (starting at approximately $350).
