I spent yesterday fiddling with my Astore.  In fact, I deleted all the books I had added earlier. The reason for this was that I wanted to sort them into categories.  So now I have four categories with 5-10 books in each.  I only selected books I have read, and liked.  Some are reviewed on the blog, some are not. I have a feeling that sooner or later, most of them will get reviewed.  Regarding the formats it is a mix of e-books, and paperbooks. It is mostly paper books, though, which is conscious decision. I love e-books, but the Geo restrictions are a hassle.
Do check it out.
