“…We consider this being good and bad news at the same time, as it underlines that GS has further improved its coverage compared to earlier publications that reported lower numbers (Chen, 2010;Meier & Conkling, 2008). On the other hand, it also supports the provisos of other researchers (Jasco, 2010) against GS as it still seems to index a lot of "ghost publications".…”

It is understandable that sponsors of research activities are interested in assessing the work of scholars they (plan to) support although this is not a simple undertaking. Until today, there is no obvious approach for objectively measuring and comparing the quality of research results from different disciplines. Hence, counting publications has been used for long time as a substitute to deal with this challenge and only recent technological advances have fostered the usage of so-called citation indices (such as the h-index) for this purpose. Although this approach is as disputed as all previous ideas in this context, we feel it is about time to investigate the expressiveness of modern citation analysis approaches in computer science more closely. In order to do that, we have chosen the area of software engineering and created a first comprehensive ranking, illustrating citation values of world class scholars by analyzing the work of almost 700 researchers in this field. We have found that top h-index scores in software engineering are around 60 while top-notch g-indices start at around 130 when Google Scholar and Publish or Perish, the quasi standard tools for this purpose are used. Clearly, the results of our study are influenced by the coverage of these tools so that we have also analyzed Google Scholar and found it having a very high coverage of software engineering publications. Hence we are convinced to have collected good quality results that will allow our community to better judge and use citation numbers in the future.

“…According to Chen (2010), Google Scholar covered 98 to 100 % from eight databases of both subscription based and publicly available journals in 2010. Five years earlier, the coverage of the same databases was only between 30 and 88 % while Meier and Conkling (2008) found a coverage of over 90 % in engineering literature.…”

“…The content of one or several databases examined is then aligned with the content of the reference database, for instance with regard to professional or linguistic structure (e.g. Meier/Conkling 2008und de MoyaAnegón et al 2007. In other studies, external publication data is processed, e.g.…”

Coverage of Business Administration Literature in Google Scholar: Analysis and Comparison with Econbiz, Scopus and Web of Science

Google Scholar is used for literature research as well as for evaluations of research performance. To establish Google Scholar's functional compliance, we generate a heuristic method and apply it to business relevant journals, namely those ascertained and rated in the German business journal ranking VHB-JOURQUAL2 by Schrader/Hennig-Thurau (2009). It is shown that Google Scholar primarily indexes international, i.e. English-language journals with a high rating grade; national language, here German-language literature, is hardly covered systematically. Furthermore, we compare these results with the business journal content of the German database EconBiz and the international databases Web of Science and Scopus. While Google Scholar is definitely competitive with Web of Science and Scopus for English-language literature, German-language literature is systematically covered by EconBiz, only. The comparison is additionally done for special business research fields. With regard to the journal coverage of some of these research areas, it becomes evident that the national database EconBiz even dominates the databases Scopus and Web of Science.

“…Further, the authors identified GS as a good starting place for undergraduate research projects. 20 In the past year, there have been even more comparisons with databases that perhaps note changes to the earlier disciplinary weaknesses. For example, Walters compared search performance in the subject area of later-life migration in GS and eleven other library subscription databases including EBSCO's Academic Search Elite, MEDLINE, SSCI, and SocIN-DEX.…”

Google Scholar Users and User Behaviors: An Exploratory Study

The University of Mississippi Library created a profile to provide linking from Google Scholar (GS) to library resources in 2005. Although Google Scholar does not provide usage statistics for institutions, use of Google Scholar is clearly evident in looking at library link resolver logs. The purpose of this project is to examine users of Google Scholar with existing data from interlibrary loan transactions and library Web site click-through logs and analytics. Questions about user status and discipline, as well as behaviors related to use of other library resources, are explored.
