Penn's Digital Collections & Projects"Digital collections and projects feature unique, primary-source materials for teaching, research, and discovery drawn from the Penn Libraries' signature collections or from our collaborations with the Penn community and with cultural heritage institutions. It provides access to important rare books, manuscripts, photographs and multimedia sources represented by images, texts, audio files, bibliographic databases, catalogs, and archival finding aids for the study of a wide array of subjects ranging from Philadelphia neighborhoods and the life of Marian Anderson to medieval manuscripts and Shakespeare's plays. In addition, this site gathers together Penn Libraries' pre-1923 materials publicly available through the Internet Archive as well as Penn-produced scholarship accessible in the ScholarlyCommons."
