First, find the item you need in GIL. (For help with GIL, try the GIL Skills tutorial.) Here's the GIL record for a book with the call number highlighted:

Write down the call number, so you can carry it to the bookshelves with you.

Figure out on which floor you'll find the book. At the Clarkston Campus Library:

• Items with call numbers that begin with the letter A through the letter M are on the third floor.
• Items with call numbers that begin with the letter N through the letter Z are on the fourth floor.
• Items with call numbers that begin with Ref are on the second floor. (These are reference books.)
• On which floor is The Salt Eaters?
