Hello,
Lost in McKeldin? There are black assistance phones located by the large elevator in the front wing, on the first column closest to the elevator, on floors 3 through 7. On the map below they're marked with a yellow dot that has an 'i' in the middle. These phones connect directly to the Library Services Desk.
But first, here's a brief alphabetical guide that may help you find call numbers. The floor plan below the guide may help you further. Most books are located in Stacks, so be careful to stay out of Folio (for tall books, located up at the front elevators) and also out of Periodical Stacks (in moveable shelves with wheels on the front, located all the way toward the back).
McKeldin Library's floor plan (along with help using it) is also available at the Library Services Desk on First Floor, TLC Tech Desk on Second, and on the Libraries' website.
