Two thirds of CCU Library's collection is in an electronic book format, also known as eBooks. To access the vast majority of eBooks follow the steps below. Most of the eBooks are for unlimited, simultaneous users. A small number of eBooks are for one user or up to three users at a time. Books that are limited to one and three users at a time are only in use as long as the person is at the book's page, unlike our print books that can be checked out for multiple days. If you're trying to access an ebook and it's in use, please wait some time and try again. An exception are eBook titles from Overdrive which may be checked out, but these are a mostly fiction and pleasure reading collection. The publisher decides on how they will offer their book.
