Adelphi University Libraries: Books

Book Collection

The Adelphi University Libraries have more than 600,000 volumes in the book collection. The books are accessible through our catalog OneSearch. The catalog contains all the records from Swirbul Library and our Centers. Adelphi students can borrow books from any of our libraries. If a book is at a different location from where the student is, the student can simply click on Request hold in the record and request the book be sent. Our book collection is arranged by Library of Congress Classification. Letters and titles are assigned by the Library of Congress; click here for a listing of the main classes.
