I'm in Geneva (with fellow wikimedians) at a OA conference and we are talking *a lot* about Wikisource. 

We have found a very high quality publisher of OA books (http://www.openbookpublishers.com/, released in CC-BY), that would be utmost happy to have their books in Wikisource. 

I think the first issue is technical:

* do we have a tool that easily takes an EPUB/HTML and convert it in books in Wikisource? I'm thinking now about ns0, not nspage. 

I think that if we can take a HTML/EPUB index, and transform it in a draft Wikisource index of links, and upload all the chapters, formatted, we would have done the 90% of an upload of a book.

This would be really important to insert up to date, high quality OA content in Wikisource, easily accessible for Wikipedians too. 

And, moreover, Open Access books are more relevant to Wikisource than Open Access articles (IMHO).
