I went on a small tangent yesterday about an ereader and today I found yet another ebook site. ManyBooks.net claims to have 18000 free ebooks for download to pdas, ipods and ereaders.
Many of the books on this site I have seen on other free ebook sites (Project Gutenberg – who have by the way really improved their site), but there is a nice feature here where you can see the top downloaded books and reviews from readers as well.
