Difflugia I'm wondering if you'd like to start a thread in the General Discussions sub-forum (that is, this sub-forum) explaining about the Google ebook site. I think that, like the other book seller sites, there's a bit to get across to understand how the site explains things and how it works etc.
A number of the posts in this thread have related to that topic and could be moved into the new thread as well.
I think that a greater audience of MR members would benefit from the dedicated thread than just those of us who are participating in this thread.
Anyway, up to you .... but I know that I've benefited greatly by what you've said/explained so far.
(Maybe the title of the thread could be something like: Buying Google Books - a Guide [or whatever])
