One of the problems which face all librarians adding e-books to their collections is that of bibliographic control: there is no legal deposit for e-books and consequently there is no single place from which new titles can be found. If this is true of commercially published e-books, it is most certainly also true of free e-books... and there are many thousands of free e-books available over the Internet, many of which are of a quality such that librarians might wish to have them in their collections. The 2011 Guide to Free or Nearly-Free e-Books is offered as a tool for librarians and others involved in book selection (e.g. teachers in schools) in all sectors - school, further and higher education, public and special libraries - to facilitate easy access to free e-books and e-book collections which can enhance their digital library.
