Duquesne's proximity within blocks of the Pittsburgh region's legal center makes its law library, the Center for Legal Information, one of the area's major sources for legal research and information services. The Center's facility spans three floors within Hanley Hall and houses a growing collection of nearly 250,000 volumes.
The Center provides students and faculty with excellent access to electronic legal resources. The Web, as well as key legal databases such as LEXIS, WestLaw, and HeinOnline, may be accessed from any of the Center's 78 student computers. Law students with laptop computers may access the Web from anywhere in the Center through the wireless network program.

Students have access to ample study space throughout the Center. In particular, the first floor features a spacious reading room with study carrels, tables and an informal popular reading area. Additional seating is available on the second and ground floors. Group study rooms are also available.

The Center's physical collection features a comprehensive Pennsylvania law collection, a core collection of American and English law, together with leading treatises, textbooks, loose-leaf services, and international law materials. The Center is also a United States Government Depository.

To help students and legal practitioners make the most of electronic and traditional legal resources, the Center's professional staff conducts systematic and continous training programs in all aspects of legal research.

In 1999, Duquesne University entered into an historic agreement with the Allegheny County government to manage its 137-year-old County Law Library, one of the largest county law libraries in the country. As a result, Duquesne law students have direct access to this historic and rich collection and the reading room facility of the ACLL.
