Im looking for a good program designed to organize/manage your Ebooks and if possible, to have a way that would bookmark your page in each book. I have 6gb worth of Ebooks, mainly pdf, and I juggle about 3-4 books at a time, so I really need something with the organization of a library, and the ability to bookmark several books at a time. If anyone knows of a good program please reply, it would be greatly appreciated.
