This handbook provides an approachable introduction to building collections in the health sciences, covering a wide range of specialties including medicine, nursing, and allied health disciplines. It is designed as an essential guide to starting a new collection and one of its strengths is the curated lists it compiles of recommended books, journals, databases, websites, and other resources pertaining to those specialties. Of particular interest is a chapter dedicated to building diverse and inclusive collections, again with lists of recommended titles. However, as the book acknowledges, the health sciences are ever-evolving so readers should use this text as a starting place and should consult other supplementary texts. This open access book is authored by the Medical Library Association Collection Development Caucus and can serve as a companion text. The book under review will be most appropriate for new collection development librarians, library directors starting a new library, or liaison librarians supporting new academic programs or clinical departments. Recommended. Professionals.
