Existing research argues that studies of the value of public libraries support libraries by demonstrating their worth to society. Knowledge of research methods, value and research gaps can potentially strengthen the field of value research and support policymaking and development of libraries. Among 16,683 records retrieved from a systematic literature search, 39 studies were selected for systematic review within this topic. Findings indicate that studies focus on examining libraries as valued community assets in several aspects. It is recommended that further research explore how library services enhance democracy, reading and culture. Moreover, further research is needed that systematically reviews how libraries articulate their value to stakeholders. Concluding remarks state that value can be a robust measure for emphasising and developing libraries' worth towards society. By systematically reviewing how value is emphasized in activities, libraries are provided with the means to advocate political empathy and to develop towards community needs.

现有研究认为，对公共图书馆价值的研究通过向社会展示其价值来支持图书馆。对研究方法，价值和研究空白的了解可以潜在地加强价值研究领域，并为图书馆的政策制定和发展提供支持。在从系统文献检索中检索到的16683条记录中，选择了39项研究以对该主题进行系统评价。研究结果表明，研究着重在几个方面检查图书馆是否是有价值的社区资产。建议进一步研究探索图书馆服务如何促进民主，阅读和文化。此外，还需要进行进一步的研究，以系统地审查图书馆如何向利益相关者阐明其价值。结束语指出，价值可以成为强调和发展图书馆对社会的价值的有力手段。通过系统地回顾活动中如何强调价值，图书馆可以提倡政治同情并朝着社区需求发展。
