It should now be hard to make the statement that you have a Sony Reader and cannot find anything to read because Google has now made more than one million titles available for the Sony Reader. The newly available books, which are all public domain titles are coming courtesy of Google Books in the EPUB format. As of now, due to copyright laws, these titles are only going to be available for those in the US. However on the flip side, they are being formatted for use on either the PRS-505 or PRS-700 Reader. Current Sony Reader users will be able to find these newly available titles in the Sony eBook Store and of course they are all available as free downloads.
