Bibliometric methods are used in multiple fields for a variety of purposes, namely for research evaluation. [] Key Result As a consequence, the results of bibliometric analyses may vary depending on the database used. These results imply that in the context of comparative research evaluation, WoS and Scopus should be used with caution, especially when comparing different fields, institutions, countries or languages.
The Journal Coverage of Web of Science, Scopus and Dimensions: A Comparative Analysis
TLDR
The results indicate that the databases have significantly different journal coverage, with the Web of Science being most selective and Dimensions being the most exhaustive.
A tale of two databases: the use of Web of Science and Scopus in academic papers
TLDR
It is revealed that although both Web of Science and Scopus are increasingly used in academic papers, Scopus as a new-comer is really challenging the dominating role of WoS.
Coverage of highly-cited documents in Google Scholar, Web of Science, and Scopus: a multidisciplinary comparison
TLDR
The main conclusion is that the data about highly-cited documents available in the inclusive database Google Scholar does indeed reveal significant coverage deficiencies in Web of Science and Scopus in several areas of research.
A Criteria-based Assessment of the Coverage of Scopus and Web of Science
TLDR
The relative coverages of Scopus and Web of Science are compared with regard to publication type, field of research and language and the results show that Scopus covers 72 percent of the total Norwegian scientific and scholarly publication output in 2015 and 2016.
Journal coverage of the Emerging Sources Citation Index
TLDR
This study analysed 6,296 ESCI‐indexed journals to determine their inclusion in 105 databases and found that 19.3% of the ESCI journals are not covered by any other A&I databases, a high figure compared with only 0.5% SCIE, 0.3%, SSCI, AHCI, and 5% Scopus journals, which suggests that the selection criteria for ESCI Journals are not consistent with the overall trend in the other classical citation indexes.
The coverage of Microsoft Academic: analyzing the publication output of a university
TLDR
It is concluded that MA is on the verge of becoming a bibliometric superpower and shows biases similar to Scopus and WoS with regard to the coverage of the humanities, non-English publications, and open-access publications.
Web of Science and Scopus language coverage
TLDR
The most comprehensive source for each language and research area were identified and some coverage problems have been found in the bibliometric database used.
Assessing the publication impact using citation data from both Scopus and WoS databases: an approach validated in 15 research fields
TLDR
This study increased the reliability of its previous conclusions that the percentile rank can be used as a citation database-normalization, and revealed a substantial concordance between percentile ranks of papers indexed in these two databases in all the research fields studied.

Web of Science and Scopus: a journal title overlap study
TLDR
Calculations of the overlaps between the journal lists of Web of Science and Scopus and some other major scientific databases are presented, providing some measures of the overall title coverage as well as the amount of unique material in the sources studied.
Comparing Bibliometric Statistics Obtained from the Web of Science and Scopus
TLDR
Using macrolevel bibliometric indicators to compare results obtained from the WoS and Scopus provides evidence that indicators of scientific production and citations at the country level are stable and largely independent of the database.
Impact of data sources on citation counts and rankings of LIS faculty: Web of science versus scopus and google scholar
TLDR
Results show that Scopus significantly alters the relative ranking of those scholars that appear in the middle of the rankings and that GS stands out in its coverage of conference proceedings as well as international, non-English language journals.
LIS journals scientific impact and subject categorization: a comparison between Web of Science and Scopus
TLDR
The study compares the coverage, ranking, impact and subject categorization of Library and Information Science journals, specifically, 79 titles based on data from Web of Science and 128 titles from Scopus to reveal the changes in journal title rankings when normalized.
Benchmarking scientific output in the social sciences and humanities: The limits of existing databases
TLDR
There is a 20 to 25% overrepresentation of English-language journals in Thomson Scientific's databases compared to the list of journals presented in Ulrich, which means Thomson Scientific databases cannot be used in isolation to benchmark the output of countries in the SSH.
The place of serials in referencing practices: Comparing natural sciences and engineering with social sciences and humanities: Research Articles
Journal articles constitute the core documents for the diffusion of knowledge in the natural sciences. It has been argued that the same is not true for the social sciences and humanities where

Sources of Google Scholar citations outside the Science Citation Index: A comparison between four science disciplines
TLDR
An important corollary from this study is that Google Scholar’s wider coverage of Open Access (OA) web documents is likely to give a boost to the impact of OA research and the OA movement.
The place of serials in referencing practices: Comparing natural sciences and engineering with social sciences and humanities
TLDR
The results show that journal literature is increasingly important in the natural and social sciences, but that its role in the humanities is stagnant and has even tended to diminish slightly in the 1990s.
