Subject Locator & Email Query Guide


This screen permits you

to identify the location in the Main Library of materials on the subject of your interest, using the Dewey Decimal and the Library of Congress (LC) classification systems, and
to email Library departments your queries on subjects in which they specialize. The hot links will transfer you to the Web page of the Main Library Department that, in most cases, covers your topic. From that page you can directly email your question.

Please be aware that

the Children's Department,
the Foundation Center,
the Job and Career Education Center,
and the Pennsylvania Department
maintain collections that range across many different subject areas.

You may find that your query has been forwarded to another Department, more equipped to answer and respond.
