Not all the books in the library are kept on the shelves.  In fact, thousands of books are available in electronic format and reside in various library databases, such as Ebooks on EBSCOhost, ebrary Business and Economics Collection and Psychology and Social Work Collection, Gale Virtual Reference Library, Oxford Reference Online, PsycBOOKS, Salem History Database, Credo Reference and others.  Most electronic books are catalogued in eCatalog just like any other book (see Note below). They can be identified by the [electronic resource] designation after the title. They will also have either the E-Book prefix before the call number or the name of the database.  Electronic books are digital, full-text versions of print books. They are available 24 hours a day and can be accessed from any computer with an internet connection. There is no need to come into the library to use an electronic book. This makes life much easier for online students.  The following eBook came up in the results when using the search terms cloud computing.
