The Archives Service Center (ASC) is one of the main repositories within the University Library System at the University of Pittsburgh and houses collections of various manuscripts, media, maps, and other materials of historical, social, and scientific content.

[1] Some of the history of Pittsburgh and the western Pennsylvania region has been documented by primary sources such as manuscripts, books, maps, personal diaries, audio recordings, photographs, and other materials from the past.

[2][3] Some of ASC's major collections include: Often, when the estate of a notable person dies, the family donates historical documents, physical objects, photographs, and other materials that they wish to have preserved.

Individuals and organizations that research drilling, 'fracking', and the foundations of buildings, roadways, and other structures often visit the ASC to examine the maps to establish the safety and accuracy of their projects.
