Demography Library

The collection contains over 35,000 titles. The Demography Library contains a strong collection of research material on demographic research and methodology. There are also strong holdings in demographic history, economics, migration, family studies, labor issues, women, family planning, and aging and health. Geographic coverage is worldwide, with particular emphasis on Africa, Latin America and other developing regions. The Demography Library also provides access to data sets and databases on CD-ROM. In addition to the resources available via the Demography Library, PSC researchers have access to a wealth of both print and electronic resources and many other services via the Penn Libraries.

The Library, including its study and meeting spaces, are open to the public during normal operating hours between 9 am to 5pm, Monday through Friday, as long as the space is not reserved. After normal hours starting at 5 pm as well as on the weekends, the Library is open to all faculty, staff and students of the PSC as well as graduate students, faculty and staff of Criminology, Economics, and Sociology. Please contact Library staff for information about after-hour access. 

Since the library staff provides several services to the PSC community we are not always available at our desks and are often helping other researchers, working elsewhere in the building, in a meeting or running an errand. If we are not available to assist you right away please email us or call us and will get back to you as soon as we can. We have a notification board sitting on the front counter which we use daily to communicate important information, including information on where we can be found or when we will be back if we are not in the library.


Circulation: Library staff provides access to the material if the Demography Library, keeps track of circulating material with our online catalog and provides assistance with recalling material that is overdue and/or checked out to other users.

Course Reserves: Space is allotted in the library for Demography, Sociology and Economics course material. Library staff maintains, prepares and provides access to course reserve readings for Demography courses and also manages the circulation of course reserve material. If you are teaching a Demography course or course that is required for Demography students and would like printed versions of your reading lists made available in the Demography Library please contact the library staff before the beginning of the semester to ensure reading material is available on course reserve by the time the semester begins. Library staff sends a notice out to faculty teaching Demography courses prior to the start of each semester informing faculty of the services.

Acquisitions: Library staff welcomes suggestions for new material to be purchased for the Demography Library collection.
