Established in 1765 as the nation’s first medical school, the Perelman School of Medicine is now over 250 years old and is consistently ranked as one the nation’s top medical schools. There are 47 departments, divisions, and centers in the Perelman School of Medicine. The school has a full-time faculty of 2,914; over 750 medical students; 1,490 residents and fellows; and 782 postdoctoral fellows.

For nearly 150 years the physicians and students of the Medical School relied on the Library of the College of Physicians. In 1931, the rotunda of the Medical Laboratories Building, now the Morgan Building, was set aside for a Medical School Library. The collection was formed by the merger of several departmental libraries and the personal collections of several faculty members. Acquisitions for the Medical Library focused on the basic sciences and research needs of the Penn medical community. It was understood that the clinical information needs of the staff were handled by the Hospital of the University of Pennsylvania (HUP) departmental libraries and, from 1952, by the consolidated HUP Library. In 1987, the HUP library was closed, and its unique holdings were transferred to the Biomedical Library. As a consequence, the Biomedical Library was charged with providing a clinical as well as a research collection. In 2022, the Biomedical Library was renamed the Holman Biotech Commons after an extensive renovation.

The Medicine collection primarily supports the clinical education and research needs of the Perelman School of Medicine (PSOM), the Biomedical Graduate Groups, and the University of Pennsylvania Health System (UPHS) which includes the following owned hospitals: Hospital of the University of Pennsylvania (HUP), Penn-Presbyterian Medical Center (PPMC), Pennsylvania Hospital (PAH), and the Pavilion. The library does not purchase resources or tools whose primary utility is for clinical use in the health system.  However, the library does purchase clinical resources that are important for teaching health sciences students, residents, and other trainees about evidence-based practice, differential diagnosis, and anatomy. The collection also indirectly supports the Nursing, Dental and Veterinary programs. For a more complete review of these collections, see the Nursing, Dental Medicine, and Veterinary Medicine collection policies.

The collection is almost entirely electronic and consists of journals, books, clinical resources, point of care products, and databases. Additional resources include USMLE test banks, anatomy products, systematic review tools, and drug reference tools. Where possible, the collection aligns with the strategic mission and values of the library. For example, transformative open access journal agreements are sought that are both sustainable and equitable. Preference is given to Subscribe to Open agreements, but other models are reviewed to see if they benefit the university and the scholarly communication ecosystem as a whole. New and emerging formats are also collected, such as research workflow tools, datasets and apps, when their licensing models permit access for all Penn authorized users, protect user privacy, support Fair Use, and align with our current authentication and authorization services. 

The collection also works in collaboration with the Biomedical Research collection, and both serve as the main drivers of what is to be considered the Holman Biotech Commons collection. 

1. Chronological

Current publications.

2. Formats

 The preferred format for all resource types is electronic. Access via the publisher's website is preferred over access via an aggregator database. Textbooks are collected only in support of coursework. Handbooks, laboratory manuals, and loose-leaf services are rarely purchased in print and are given greater consideration when available online. Programmed texts, workbooks, and examination reviews are purchased selectively. Streaming media and apps are selectively purchased. Datasets are collected only when requested and must meet selection criteria.  Microforms are excluded, as is individual membership access. 

3. Geographical

Material may be from anywhere in the world if written in English. The undergraduate medical education collection emphasizes North America and Western medicine, as that more closely aligns with the curriculum. However, research about healthcare and medicine in other countries is acquired on a limited basis. 

4. Language


5. Publication Dates

Publications issued within the previous three years. Older materials are purchased in support of new programs, or at the specific request of faculty members. Missing volumes are selectively replaced. Digital archives are added when funding permits. 

Serials are purchased through EBSCO Subscription Services, journal aggregators, individual publishers, and through consortia agreements. The collection development librarian maintains a slip approval plan with GOBI and uses Rittenhouse Books for supplemental collecting. The monograph collection is acquired mainly in electronic format using various e-book vendors and publishers. The publisher platform is preferred; however, books are purchased on other platforms such as EbscoHost and Proquest. Frontfiles and subject packages make up a large part of the electronic monograph collection. Approval plans, search alerts, and vendor communications are used to identify new material for the collection.
