If you have problem that public library PDF and ePUB cannot coexist on my reader. you can’t open library ebook on sony reader PSR-600,  it show error message “Protected Page”.

Some library books are Adobe PDFs, some are Adobe EPUB (both DRM protected). You can have one or the other – not both types of DRM – on the Reader.

From the Sony website (this was for the 505, but I’m sure it is the same for the 300 and 600).

This issue happens when Adobe DRM protected ePub and PDF eBooks which have been borrowed, both exist on the Reader.

You can borrow epub and pdf books from your library, but be careful to never have both epub and pdf library books on your reader at the same time, as there is a conflict and you will not be able to access them. A Protected Page! error occurs on the Reader when opening a borrowed book that is in the ePub or PDF format when borrowed Adobe DRM-protected ePub and PDF eBooks exist on the Reader at the same time.

To solve this issue, please follow these steps:

1. Delete all borrowed books from the Reader and transfer them again from Adobe Digital Editions or eBook Library.
2. Verify that all borrowed books are of the same format(ePub or PDF) before transferring them to the Reader.

EPUB is a free and open e-book standard by the International Digital Publishing Forum (IDPF). Files have the extension .epub.

EPUB is designed for reflowable content, meaning that the text display can be optimized for the particular display device used by the reader of the EPUB-formatted book. The format is meant to function as a single format that publishers and conversion houses can use in-house, as well as for distribution and sale.

An EPUB file can optionally contain DRM as an additional layer, but it is not required by the specifications. In addition, the specification does not name any particular DRM system to use, so publishers can choose a DRM scheme to their liking. However, future versions of EPUB (specifically OCF) may specify a format for DRM.

Google Books

Google Books (previously known as Google Book Search and Google Print) is a service from Google that searches the full text of books that Google has scanned, converted to text using optical character recognition, and stored in its digital database. The service was formerly known as Google Print when it was introduced at the Frankfurt Book Fair in October 2004. Google’s Library Project, also now known as Google Book Search, was announced in December 2004.

Results from Google Book Search show up in both general web search at google.com and through the dedicated Google Books site (books.google.com). Up to three results from the Google Books index may be displayed, if relevant, above other search results in the Google Web search service (google.com).
