To renew a book, the first step is to sign in to eCampus. Next, select the library website http://libraries.adelphi.edu/, and click on the yellow tab "My Library Record" on the upper right of your screen. You will then be taken to a page that lists all of the books you have checked out, with an option to renew any or all of them. As an alternative, you can call Access Services at 516-877-3570.
