Should the term "Open Access" be restricted to materials with licenses that allow redistribution, like Creative Commons licenses? Or, as some advocate, only materials that allow remixing and commercial re-use, like CC-BY and CC-BY-SA?
Of those 1,076 books are in a program they call "Open Access Fremium". With these books, you can read them on the OpenEditions website for free, without having to register or anything. You can even embed them into your blog. So for example, here's Opinion Mining et Sentiment Analysis by Dominique Boullier and Audrey Lohard:
So is it OpenAccess™?
In this freemium model, the main product that's being sold is access to the downloadable ebook- whether PDF or EPUB. For libraries, a subscription allows for unlimited access with IP address authentication along with additional services. Creative Commons licenses, all of which allow for format conversion, wouldn't work for this business model because the free HTML could easily be converted into EPUB and PDF. They have their own license, you can read it here.
This is clearly not completely open, but there's no doubt that it's usefully open. For me, the biggest problem is that if OpenEditions goes away for some reason- business, politics, natural disaster, or stupidity, then the ebooks disappear. Similarly, if OpenEditions policies change or urls move, they could break the embed.
On the plus side, OpenEditions have convinced a group of normally conservative publishers of the advantages of creating usefully open versions of over a thousand books. It's a step in the right direction.
