The eBookShelf is a program you can use to organize and manage your eBook collection. Using a graphical, virtual bookshelf, it can control unlimited numbers of eBooks on unlimited numbers of Shelves (limited only by your computer's storage capacity). With the eBookShelf, you are able to organize your eBooks by author, genre, subject, or whatever method you'd like, naming the shelves the books are in as you wish. You can move, copy, and rename books, as well as mark them to differentiate them further.
