A couple of weeks back we had a new release of the epub validation tool as the old one was not validating documents properly. epubcheck-1.0.3 was released to fix the XMLParser as it was not allowing multiple validators to be added.

In my last post I talked about the epubBooks Project and how I plan to convert Project Gutenberg .txt eBooks to the ePub format and how I will make these eBooks available for download from ePubBooks.com.

Before I attempt to write this converter I will need to have a much better understanding on how a book is laid out inside the ePub OEBPS Container Format (OCF) .zip archive.
