Lewandowski D. Google Scholar as a tool for discovering journal articles in library and information science. Online Information Review 2010; 34(2):250-262
The purpose of this paper is to measure the coverage of Google Scholar (GS) for 35 major Library Information Science (LIS) journals from the years 2004 to 2006, and to collect information on the type of their availability (abstract, preprint full text, free PDF, and PDF for a fee). The results show that GS was able to index 100% of the articles for only eight journals, however for most journals the coverage ratio was over 95%. The availability of articles depends on the type of publisher and it varies a lot from journal to journal. Then GS cannot substitute for abstracting and indexing services but it can greatly help in obtaining available full texts of the desidered publications.
