You can return your books by dropping them off in the book drop bins right outside of the library on the quad side or just inside the classroom side of the building.

You can also hand your book directly to a library employee at the Main Desk during operating hours. This includes books owned by UIS, any other IShare libraries, and books obtained through Interlibrary Loan.
If you have been reading a book in the library and are unsure where you got it from, you can always leave these items on book returns.
