When you have collected the book(s) from the shelves, or if you have requested it from the MARS system, present your WolfCard ID at the Library and Research Services Desk on the 2nd (Main) floor. The book is then checked out to you. If you would like some assistance locating the book, just ask at the same desk and they will help you find what you need.
There is also a self-checkout machine next to Library and Research Services Desk.
Multimedia materials and equipment are checked out at the Multimedia Desk in the @One area on the first floor.
