As libraries strive to maintain collections with limited space, many have turned to high-efficiency, off-site shelving facilities. This work addresses virtually all major issues in planning, building, and operating high-density storage. Using the Harvard Depository model, but applying the issues and activities to other models as well, a host of contributors cover such issues as governance and cost, design and construction, preservation, selection, pre-shelving preparation, systems, access and management, services, and transportation. An essential guide to anyone considering or involved in high efficiency shelving, this book is also a valuable reference.
