To summarize the context, history and results of research studies conducted on the value and impact of health library and information services by the author since 1975 and to use this as a basis for examining ongoing developments related to evaluation research. To provide a comprehensive bibliography of library value and impact studies.
Literature review and background based on personal involvement in the studies under discussion.
The author's studies demonstrate an ongoing evolution of value and impact studies since the mid-1970s. In health sciences libraries, the approach taken to measuring value and impact has been strongly influenced by the type of research being conducted in the health sciences field as a whole. As a result, health sciences library researchers have become early adopters of methods that incorporate outcome and impact measures and rigorous research designs, and the concept of evidence-based library and information practice. The paper recommends that a range of research approaches from various disciplines be used to guide future evaluation research.
Value and impact studies will continue to be important resources for evidence-based practice as health information professionals deal with evolving user needs and new ways of delivering information to a variety of audiences.
总结作者自1975年以来开展的关于健康图书馆及信息服务的价值和影响的研究的背景、历程与结果，并以此为基础审视与评估研究相关的当前发展情况。提供一份关于图书馆价值和影响研究的综合文献目录。
基于个人参与所讨论研究的文献综述及背景情况。
作者的研究表明，自20世纪70年代中期以来，价值和影响研究不断发展。在健康科学图书馆领域，衡量价值和影响的方法深受整个健康科学领域所开展研究类型的影响。因此，健康科学图书馆研究人员早早采用了纳入结果和影响衡量指标以及严谨研究设计的方法，以及基于证据的图书馆与信息实践的概念。本文建议运用来自不同学科的一系列研究方法来指导未来的评估研究。
随着健康信息专业人员应对不断变化的用户需求以及向各类受众传递信息的新方式，价值和影响研究仍将是基于证据的实践的重要资源。
