Preservation survey (also known as condition survey, conservation needs survey or preservation assessment) is the process of collecting and analyzing data about the physical condition of library materials. Preservation surveys are used by libraries to determine the condition of their collections and identify necessary actions for preserving, conserving or repairing materials. They are most often conducted at research and university libraries. Preservation surveys are often the first step when planning and implementing a preservation program in a library. By collecting data and compiling statistics about a collection’s condition, library staff can determine environmental threats and preservation needs. It is also possible to use the resulting data to predict future deterioration.〔Robert DeCandido. “Condition Survey of the United States History, Local History and Genealogy Collection of the New York Public Library,” ''Library Resources and Technical Services'', 33,3 (July, 1989), 281.〕 Since preservation needs usually well exceed an institution’s resources, the data acquired in an assessment can aid libraries in establishing priorities in regard to deteriorating materials.〔Brian J. Baird, Jana Krentz, and Brad Schaffner, “Findings from the Condition Surveys Conducted by the University of Kansas Libraries,” ''College and Research Libraries'', 58, 2 (March 1997), 115.〕 As Ross Harvey wrote in his ''Preservation in Libraries'', the data from surveys can "be used to plan how best to deploy available resources."〔Ross Harvey, ''Preservation in Libraries: Principles, Strategies and Practices for Librarians'', London: Bowker-Saur, 1993, pg. 55〕 ==History== The need for surveying library materials was born of the increasing awareness of the problem of brittle books. William Barrow’s ''Deterioration of Book Stock: Problems and Remedies'' from 1959 alerted the library world to the alarmingly short shelf life of books composed of acidic paper. While major libraries had estimated high percentages of acidic books,〔Gay Walker, Jane Greenfield, John Fox, and Jeffrey S. Simonoff, “The Yale Survey: A Large-Scale Study of Book Deterioration in the Yale University Library,” ''College and Research Libraries'', 46 (March 1985), 111.〕 it wasn’t until 1979 that an empirical study was conducted on a library collection to determine its condition. This study,〔Sara Buchanan and Sandra Coleman, “Deterioration Survey of the Stanford University Libraries Green Library Stack Collection,” In ''Preservation Planning Program Resource Notebook'', comp. Pamela W. Darling (Washington DC: Association of Research Libraries, Office of Management Studies, 1987): 159-230.〕 at Stanford University’s Green Library, was a benchmark in the field and established the methodology for conducting preservation surveys in research libraries. Yale University conducted a large-scale assessment of its library materials in 1985〔Gay Walker, Jane Greenfield, John Fox, and Jeffrey S. Simonoff, “The Yale Survey: A Large-Scale Study of Book Deterioration in the Yale University Library,” ''College and Research Libraries'', 46 (March 1985), 111-132.〕 that is also considered a landmark in the field. Yale’s survey sounded the warning bell for research libraries worldwide, discovering that 86% of the more that 36,500 books in the sample were either brittle or composed of paper with an acidic pH.〔Gay Walker, Jane Greenfield, John Fox, and Jeffrey S. Simonoff, “The Yale Survey: A Large-Scale Study of Book Deterioration in the Yale University Library,” ''College and Research Libraries'', 46 (March 1985), 111.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Preservation survey」の詳細全文を読む スポンサード リンク
