Hello Phil,
No to all. As stated, it allows the user to add books (records) using data from Google Books.
There will be copyright issues allowing to upload/download books. Each country may have its own regulations, etc. Of course someone can upload their own books and offers them to download but I’m pretty sure this will be an exception, so no plans for this on a near future. Need to give some thought on this as I don’t have much information right now.
