Libraries use classification systems to organize the books on the shelves. A classification system uses letters and/or numbers (Call Numbers) to arrange the books so that books on the same topic are together. This arrangement can result in serendipitous browsing, where you find one book in the catalog, go to the shelf, and, an even better book is sitting right next to it.

The Ort Library uses Library of Congress (LC) call numbers for most of its collection.
You might be familiar with the Dewey Decimal Classification System from high school or the public library. Most colleges and universities use the Library of Congress (LC) Classification System because it accommodates larger collections and facilitates academic research.
The Library of Congress Classification System is subject-based, classifying and arranging items by the subject matter involved.
To check out a book found in the Stacks (4th or 5th floors), you need to go to the Circulation Desk.
Location: 3rd Floor of the Ort Library, to the right of the Main Entrance
Undergraduates can check out books for 28 days. You can renew a book if it hasn't been requested by someone else.
