The ninth edition of this popular overview of the various programs and services offered by libraries offers best practice and useful tips for implementing them effectively. Building on the strong foundation of the previous editions, award-winning author G. Edward Evans returns with a new co-author, Stacey Greenwell, for this update that combines their signature style of textbook readability, informality, and sometimes humor, as well as their knack for balancing foundational topics and new trends. A new feature in this edition is the incorporation of the concept of "library social work" through "Social Work Connections" sidebars in each chapter. Anecdotes throughout the text and "Career Connections" sidebars offer practical advice and specific current examples. Greenwell and Evans have combined several chapters from the previous edition and expanded discussions of new trends while retaining and updating the fundamentals. The ninth edition is a welcome update for library and information science courses and a valuable handbook for public services librarians.
