What do I do if I can’t find a book on the shelf?

From Guides

If the ALADIN Catalog indicates that a book is available, but it’s missing on the shelf, here are your options. First, if you can, Ask a Librarian for help (4 eyes are better than 2). Second, you may check the pre-shelving areas on the 4th, 5th and 6th floors, which are the shelves to your right as you enter the glass doors on each floor. Third, if all else fails, fill out a Missing Book Search form at the Circulation Desk.
