This article provides suggestions for librarians who are planning for the construction of new library buildings or the renovation or conversion of older buildings. The recommendations are based on practical experience gained by a Director of University Libraries in the planning and construction of Tompkins-McCaw and James Branch Cabell Libraries at Virginia Commonwealth University. Reference throughout the article is made to the writings of five recognized authorities in the field of library building construction and furnishings: Ralph E. Ellsworth, Ellsworth Mason, Keyes D. Metcalf, William S. Pierce, and Godfrey Thompson. Particular attention is given to areas inadequately recognized by these authors including exteriors of library buildings, building approach and access, bicycle accommodations, lighting, sprinkler systems for fire protection, carpeting of floor surfaces, wall coverings, pest control, pesticide treatments, and refuse disposal. The role of the librarian in architectural planning, and the importance of hiring a library building consultant and utilizing library service statistics when planning a library building are also considered. The article concludes with two lists outlining cost and capacity figures for the Tompkins-McCaw and James Branch Cabell Libraries, and a six-item bibliography. (Author/ESR)
