What Does a Medical Librarian Do?
What does a medical librarian actually do on a typical workday? The short answer: they connect clinicians, researchers, and students with the biomedical evidence they need to make decisions, and they do it fast enough to matter at the point of care.
Core Research and Search Duties
Medical librarians spend a large share of their time running expert literature searches for physicians, nurses, and faculty investigators. That means fluency with PubMed, CINAHL, Embase, Cochrane Library, and Scopus, along with the controlled vocabularies (MeSH, CINAHL headings) that make those databases searchable at a professional level. They also support systematic reviews and evidence syntheses, often as co-authors, by designing reproducible search strategies, documenting them per PRISMA standards, and managing citation screening in tools like Covidence or Rayyan.
The Clinical Informationist Role
A growing subset of medical librarians work as clinical informationists (sometimes called informationists or embedded librarians). Rather than waiting in the library, they join morning rounds, sit in on tumor boards, and answer point-of-care questions from the care team in real time. When an attending asks about the latest evidence for a treatment protocol, the informationist pulls, appraises, and summarizes the literature within the clinical workflow, not days later.
Teaching and Instruction
Instruction is a substantial part of the job in academic medical centers. Medical librarians teach medical students, residents, and graduate researchers how to search efficiently, evaluate study quality, use citation managers like EndNote or Zotero, and navigate evidence-based practice frameworks such as PICO. Many hold faculty appointments and contribute to curriculum design.
Titles, Settings, and Operational Work
The titles "medical librarian" and "health sciences librarian" are used interchangeably, though the work environment shapes daily priorities. Hospital librarians focus on clinical support and patient education. Academic medical center librarians balance instruction, research consultation, and systematic review work. Pharmaceutical and biotech librarians support drug development pipelines and regulatory submissions. VA and government health librarians serve clinicians across large distributed systems.
Behind the scenes, medical librarians also handle collection development and digital resource licensing: negotiating journal package contracts, managing e-book platforms, tracking usage data, and stretching acquisitions budgets against rising subscription costs. It is quieter work than clinical rounding, but it is what keeps the databases and journals accessible in the first place.
