<p>A library's primary function is to provide access to information considered useful or valuable to the society in which they exist. True to their introduction, Evans and Carter provide a solid, broadly based view of library public service and its functions. As in the preceding edition, its authors marry the importance of the help ethos with a plethora of technological tools and techniques. Coverage of such essential topics as circulation, reference, interlibrary loan, literacy instruction, reserves, and security has been extended, updated, and predicated on the importance of keeping a watchful eye on ethical and legal implications. New to this edition are discussions of staffing and training, customer service, programming, and assessment. The result brings into focus the duties and responsibilities of both professional librarians and support staff, with particular emphasis on areas of common concern.</p>
