The study aims to discover the information sources most suitable for exploratory searching in terms of effectiveness and content coverage in searching for library and information science (LIS) scholarly publications on a specific topic. It is intended to support LIS researchers in the choice of a search system in situations when they start exploring a topic and try to find the necessary literature. Four information sources were selected after a preliminary survey: Google, Google Scholar (GS), Ebsco Discovery Service (EDS), and Library and Information Science Abstracts (LISA). They were compared based on query results in terms of precision, relative recall, coverage, and full-text access. In all these aspects Google turned out to be the best. GS was close behind, followed by LISA and EDS.

该研究旨在从搜索特定主题的图书馆和信息科学 (LIS) 学术出版物的有效性和内容覆盖率方面发现最适合探索性搜索的信息源。它旨在支持 LIS 研究人员在开始探索主题并尝试查找必要文献时选择搜索系统。初步调查后选择了四个信息来源：Google、Google Scholar (GS)、Ebsco Discovery Service (EDS) 和 Library and Information Science Abstracts (LISA)。根据查询结果在精度、相对召回率、覆盖率和全文访问方面对它们进行比较。在所有这些方面，谷歌都是最好的。GS紧随其后，LISA和EDS紧随其后。
