Open access at the national level: A comprehensive analysis of publications by Finnish researchers
TLDR
Institutional data, integrated at national and international level, provides one of the building blocks of a large-scale data infrastructure needed for comprehensive assessment and monitoring of OA across countries, for example at the European level.
Use of Bibliometrics Data to Understand the Citation Advantages of Different Open Access Categories in Covid‐19 Related Studies
TLDR
This research analyzed the bibliometrics data and citation numbers of around 42,000 English language articles published in 2020 related to COVID‐19 to understand the correlations between different OA types and the impact of OA research articles evaluated based on the citation numbers.
Open access availability of Catalonia research output: Case analysis of the CERCA institution, 2011-2015
The open access availability of publications by Catalonia’s CERCA research centres was analysed to determine the extent to which authors use open access journals, repositories, social networks and
Grades of Openness: Open and Closed Articles in Norway
Based on the total scholarly article output of Norway, we investigated the coverage and degree of openness according to the following three bibliographic services: (1) Google Scholar, (2) oaDOI by
Evolving landscape of scholarly journals in open access environment
Purpose Open access journals (OAJs) offer immediate, free and unrestricted online access to the scholarly literature. The purpose of this study is to trace the status and characteristics of OAJs
Is open access publication useful for all research fields? Presence of funding, collaboration and impact
TLDR
It is possible to venture that OA publishing will be useful for all research fields, although their specific features should be considered, and funders should be aware of these particularities to stimulate OA without compromising the quality of the research.
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.
Open access uptake in Germany 2010-2018: adoption in a diverse research landscape
TLDR
The results of this study can serve as a baseline to assess the impact recent transformative agreements with major publishers will likely have on scholarly communication and show that subject-specific repositories are the most prevalent type of OA.
Does open access citation advantage depend on paper topics?
TLDR
It is concluded that OA authors’ self-selectivity, if it exists at all, is not responsible for the OA citation advantage, at least as far as selection of topics with probably higher citation potentials is concerned.
What happens when a journal converts to Open Access? A bibliometric analysis

Developing indicators on Open Access by combining evidence from diverse data sources
TLDR
This study presents a methodology that systematically creates OA labels for large sets of publications processed in the Web of Science database based on the combination of diverse data sources that provide evidence of publications being OA.
Open Access to the Scientific Journal Literature: Situation 2009
TLDR
The results show that OA already has a significant positive impact on the availability of the scientific journal literature and that there are big differences between scientific disciplines in the uptake.
Google Scholar versions: do more versions of an article mean greater impact?
TLDR
Investigating GS versions as an alternative source for a scholarly article to break new ground in understanding the various versions GS indexes, correlations between the number of GS versions and citation counts, and the value of institutional repositories for increasing scholarly impact.
Google Scholar as a source for scholarly evaluation: A bibliographic review of database errors
TLDR
The results indicate that the bibliographic corpus dedicated to errors in Google Scholar is still very limited, excessively fragmented, and diffuse; the findings have not been based on any systematic methodology or on units that are comparable to each other, so they cannot be quantified, or their impact analysed, with any precision.
The journal coverage of Web of Science and Scopus: a comparative analysis
TLDR
Results indicate that the use of either WoS or Scopus for research evaluation may introduce biases that favor Natural Sciences and Engineering as well as Biomedical Research to the detriment of Social Sciences and Arts and Humanities.
Open access and sources of full-text articles in Google Scholar in different subject fields
TLDR
The aim of the study was to find out about the sources of full-text items and to look at subject differences in terms of number of versions, times cited, rate of open access availability and sources ofFull-text files in Google Scholar.
The citation advantage of open-access articles
TLDR
There appears to be a clear citation advantage for those articles that are OA as opposed to those that are TA, but this advantage varies between disciplines, with sociology having the highest citation advantage but the lowest number of OA articles from the sample taken and ecologyHaving the highest individual citation count for OAarticles but the smallest citation advantage.
Measuring compliance with a Spanish Government open access mandate

  • Medicine, Political Science
    J. Assoc. Inf. Sci. Technol.
  • 2016
TLDR
This study measures the degree of compliance with a Spanish government OA mandate 2.5 years after its implementation, and finds great potential for growth in green OA, because over two thirds of the articles that were not available as OA were published in journals whose publishers allow a preprint or a postprint copy to be deposited.
