You can request a book or other material by title or author. Simply give the information to a library staff member in person, by email, or by phone.
You can also use the ILL (Interlibrary Loan) form on the library page of the Allen website.
The book will be sent by courier to the Allen Library, and then checked out to you. You will be notified by e-mail when the book has arrived and you can then pick it up in the library.
