Hidden in Plain Sight: Musical Treasures in the Penn Library Curated by Marjorie Hassen Otto E. Albrecht Music Library University of Pennsylvania

Introduction The prospect of discovery is arguably the driving force behind archival research. Uncovering an unknown or long-lost item rewards patience, erases disappointment, and immediately compensates for years of tedium. Unsuspected connections among disparate items or collections offer, perhaps, the greatest potential for new directions. This exhibit not only highlights the richness of the Library's music-related collections but also draws attention to the treasures "hidden" in less-than-obvious places. Here are unexpected riches from among the Library's collections of books and scores and from the letters, papers, photographs, and printed and manuscript music that together document the career of an individual or the history of a cultural organization. These are random samplings, then: we wait to see where they will lead.
