To help libraries and other holdings institutions better incorporate preservation concerns in construction, renovation, and routine maintenance, various techniques are presented that allow preservation concerns to be integrated. The following topics are considered: (1) site selection; (2) design of the building envelope; (3) the library interior; (4) floor coverings; (5) roofing materials; (6) electric and plumbing features; (7) lighting; (8) environmental controls; (9) integration of fire protection and security concerns; (10) pest control; (11) use of book returns; and (12) landscaping. Cost concerns are discussed, explaining various cost analyses, the relationship between preservation and maintenance, and why preservation costs provide long-term benefits. Designing for preservation, while likely to increase the short-term capital costs of a new library building, will provide significant cost returns in longer collection life and reduce long-term maintenance and replacement costs associated with the library itself. Various phases of architectural design and construction, and their relationship to preservation concerns, are briefly outlined to help avoid common pitfalls in working with architects, engineers, and contractors. Eight figures and two tables illustrate the discussion. A list of 37 resources for preservation is included; and four appendixes provide specific details about lighting and pesticide use, and a checklist of preservation concerns. (Contains 70 references.)
