How to request books, journals and other materials that aren't available at the Marshall Brooks Library

I-Share versus Interlibrary Loan (ILL)


Interlibrary Loan (ILL)

What is it?
I-Share allows Principia College students and faculty to borrow books and multimedia items from 89 other academic and research libraries in our consortium. Items are delivered to the Marshall Brooks Library Monday-Friday. Items can also be checked out in-person at I-Share libraries with your Principia ID.

What is it?
Principia College shares items with libraries across the United States of America and Canada. If an item is unavailable through I-Share or in the Marshall Brooks library, it may be available through interlibrary loan. (Note: Textbooks are not requestable through ILL.)

How does it work?
Use Library Search @ Prin or All I-Share Libraries search to find the item you are looking for then sign in with your Principia Login. For more specifics, see the detailed instructions on Request Items Through I-Share webpage.

How does it work?
