The Friends of the Library sponsor an ongoing book sale on the lower level of the library near the escalators. There are hardcover and paperback books available when the library is open. The suggested donation for hardcovers is $1.00 and paperbacks is $0.50. We request exact change in cash at the circulation desk on the first floor; circulation desk staff cannot make change. Checks for purchases over $5.00 are also welcome.
The NIU Libraries do not accept unsolicited donations of books or other items. Please do not leave unsolicited materials on the Founders Library loading dock. If you have materials you would like to offer to us, please contact us for more information. We do not accept:
