Floorplans
Books are arranged on the shelves of the Library by shelfmarks. The Library is in the process of reclassifying its stock to a version of the Library of Congress Classification Scheme so some books will carry LC call numbers while others remain in the old broad subject categories.
Floorplans of the collections are available which indicate the location of each subject category and the new LC sequences. These can be found at each computer station and in several places around the Library. You can also download and view them here.
