Book excerpt: Collection development is a cornerstone of librarianship; and with the rapid pace that library materials are produced, a thorough knowledge of collection development is more important than ever before. However, with the myriad of choices available, creating a meaningful collection can be a daunting task. Building and maintaining a health sciences library collection can be a challenge, especially in scenarios where there is no dedicated collection services department or collection development librarian. Often in library school curriculum, collection development strategies are discussed, but specific examples of bibliographic sources may not be covered in detail, particularly for health sciences resources. Many collection development books often discuss the creation of policies, budgeting practices, and usability. This book is a comprehensive reference guide for those who will be creating and curating their library health sciences collections. Moving beyond a traditional list of titles, this guide will focus on several formats and areas. It features specific bibliographic information for top resources for a variety of subject areas and in a variety of formats. This book is designed for all librarians, whether new or experienced. Each chapter of this title does a deep dive into an area of health sciences library collection building, as well as covering how to maintain a current collection. This book is designed to provide readers with a resource to lean on in determining the best bets in providing their users with health sciences resources to support curriculum, practice, and other user needs. Readers who are interested in gleaning techniques for maintaining their health sciences library collection will also benefit from this how-to guide as it details the deselection process.
