Library of Congress Classification System: QD, Chemistry
Books and journals acquired since 1970 are classified in the Library of Congress Classification system. Many earlier books have been reclassified to LC as well, but others remain in the Dewey Decimal Classification. All Dewey materials from the Chemistry Library are in the Library Storage Facility. This is a summary with highlights of the QD Schedule, which covers Chemistry.
