Student Health & Safety;

The Health Sciences Library uses the National Library of Medicine Classification System (NLM). While there are no Ws used in the Library of Congress system, NLM uses the entire W range in its call numbers. So if you have a call number that begins with W, it is from one of the Health Sciences Libraries. NLM uses a range of starting letters from QL, QS-QZ, and W-WZ. The Health Sciences Library also uses the Library of Congress system for social sciences, biology and veterinary medicine: BF, H, QH, SF.
