Hi!
I'm a new Calibre user and tested the "get books" option yesterday. After looking for a few titles I noticed that you can find many popular books for free. And I'm not talking about DRM-free books!
The most common source for free versions of contemporary bestsellers etc. seems to be Feedbooks. But for some reason those ebooks are not free on the Feedbooks site itself.
For example, "Gone Girl" by Gillian Flynn can be downloaded for free with Calibre. It names Feedbooks as source, but if you try to download it via Feedbooks (I was able to sign in there with Google+) you have to pay for it. "Gone Girl" isn't an exception, I tried the same with several other titles that aren't free in any of the other shops listed by Calibre.
So I was wondering how Calibre is able to access these books for free and if it's legal/safe to use the "get books" option in cases like this... ? Thanks!
