National Zoological Park (NZP)Located on the grounds of the 160-acre Zoo in Washington, D.C. and the 3,100-acre campus of SCBI in Front Royal, Virginia, the Libraries supports research into species survival as well as the daily care and feeding of more than 2,400 animals of 350 different species. Opened in 1898, the library is one of the oldest in continuing existence at the Smithsonian. The Libraries’ print and online collections focus on topics such as genetics, comparative reproductive physiology, animal cognition, endocrinology, sustainability of endangered animal populations, conservation medicine, and biological diversity. Librarians also offer extensive training for staff on searching complex online databases that house medical and scientific publications.
