This document discusses how medical libraries can highlight their importance within their parent institutions. It suggests assessing user needs through surveys, interviews, and observations to understand what the library's users require. The parent institution expects the library to support high-quality education, medical services, and research. The library can do this by providing resources that enhance teaching, ensure patient safety, and support grant applications and scholarly publications. Assessing user needs directly and finding ways to meet them will help the library demonstrate its value to the parent institution.
