This book, first published in 1992, establishes a theoretical base for access services while also suggesting connections between theory and practice. It provides fresh thinking that re-examines previous writings in this area, presents new experimental designs and results, creates contemporary organizational solutions, and adopts innovative techniques for increasing users' access to library materials within constrained budgets. Access services librarians, circulation department librarians, and library managers, especially those who are considering a reorganization that will include access services, will benefit from the philosophical and theoretical articles as well as practical advice on the design, delivery, and evaluation of responsive library services. Chapters in this invaluable book fill the gap in the literature about access services including theoretical descriptions of access services, current developing trends in access services, the historical development of the access services concept, practical studies related to common access services issues, and projections of future challenges.
