Characteristics of open access scholarly publishing: A multidisciplinary study
Aslib Proceedings, 2009
Purpose -More knowledge about open access (OA) scholarly publishing on the web would be helpful for citation data mining and the development of web-based citation indexes. Hence, the main purpose of this study is to identify common characteristics of open access publishing, which may therefore enable us to measure different aspects of e-research on the web. Design/methodology/approach -In the current study, five characteristics of 545 OA citing sources targeting OA research articles in four science and four social science disciplines were manually identified, including file format, hyperlinking, internet domain, language and publication year. Findings -About 60 per cent of the OA citing sources targeting research papers were in PDF format, 30 per cent were from academic domains ending in edu and ac and 70 per cent of the citations were not hyperlinked. Moreover, 16 per cent of the OA citing sources targeting studied papers in the eight selected disciplines were in non-English languages. Additional analyses revealed significant disciplinary differences in some studied characteristics across science and the social sciences. Originality/value -The OA web citation network was dominated by PDF format files and non-hyperlinked citations. This knowledge of characteristics shaping the OA citation network gives a better understanding about their potential uses for open access scholarly research.
The dark side of open access in Google and Google Scholar: the case of Latin-American repositories
Scientometrics, 2014
Since repositories are a key tool in making scholarly knowledge open access (OA), determining their presence and impact on the Web is essential, particularly in Google (search engine par excellence) and Google Scholar (a tool increasingly used by researchers to search for academic information). The few studies conducted so far have been limited to very specific geographic areas (USA), which makes it necessary to find out what is happening in other regions that are not part of mainstream academia, and where repositories play a decisive role in the visibility of scholarly production. The main objective of this study is to ascertain the presence and visibility of Latin American repositories in Google and Google Scholar through the application of page count and visibility indicators. For a sample of 137 repositories, the results indicate that the indexing ratio is low in Google, and virtually nonexistent in Google Scholar; they also indicate a complete lack of correspondence between the repository records and the data produced by these two search tools. These results are mainly attributable to limitations arising from the use of description schemas that are incompatible with Google Scholar (repository design) and the reliability of web indicators (search engines). We conclude that neither Google nor Google Scholar accurately represent the actual size of open access content published by Latin American repositories; this may indicate a non-indexed, hidden side to OA, which could be limiting the dissemination and consumption of open access scholarly literature.
Open Access Levels and Patterns in Scholarly Articles from India
Current Science, 2019
Open access (OA) has emerged as an important movement worldwide during the last decade. There are several calls now that not only persuade researchers to publish in OA journals, to archive their pre-or post-print versions of papers in repositories, but also institutions and funding agencies to promote OA of research publications. This article examines OA levels and patterns in research output by computationally analysing research publication data obtained from the Web of Science for India during the last five years (2014-2018). Results obtained show that about 24% of research output from India, during the last five years, is available in OA compared to world average of about 30%. More articles are available in gold OA compared to green and bronze OA. Furthermore, OA levels vary in different disciplines, with medical science, physics and biology having higher percentage of their articles available as OA as compared to those like arts and humanities, social science and (surprisingly) information science.

HowOpenIsIt is a guide created by SPARC (Scholarly Publishing and Academic Resources Coalition), PLOS (Public Library of Science), and OASPA (Open Access Scholarly Publishers Association) to describe an array of policies a journal can have in the continuum between "Open" and "Closed. " The OAS Evaluation Tool uses the HowOpenIsIt guide to measure the degree of openness of journals of all kinds with scores between 0 and 100. A total of 1,005 journal samples, both OA and non-OA journals in various languages and from various parts of the world, were evaluated and scored with the OAS Evaluation Tool by a team of information professionals in 2015 based on the policies posted on journals' websites. This article reports the findings of the OAS evaluation. Literature review Generally, if a journal offers free readership rights to all its articles immediately upon publication, it is considered an
Publishing Research Quarterly, 2021
This paper offers a crosscountry and cross-disciplinary analysis of the development of open access publishing from 2000 to 2019. Through an analysis of seven world regions and nine scholarly fields, we found that, while the overall share of open access journals has increased significantly over the last two decades, there are important differences across both the analyzed world regions and disciplines. We also found that, with the exception of neuroscience, the proportion of open access journals is considerably lower among the journals ranked in the Q1 quartile of Scopus than in the general field. We also offer a model that explains the development of open access publishing trends on different disciplinary and geographical levels.

This research aims to diachronically analyze the worldwide scientific production on open access, in the academic and scientific context, in order to contribute to knowledge and visualization of its main actors. As a method, bibliographical, descriptive and analytical research was used, with the contribution of bibliometric studies, especially the production indicators, scientific collaboration and indicators of thematic co-occurrence. The Scopus database was used as a source to retrieve the articles on the subject, with a resulting corpus of 1179 articles. Using Bibexcel software, frequency tables were constructed for the variables, and Pajek software was used to visualize the collaboration network and VoSViewer for the construction of the keywords' network. As for the results, the most productive researchers come from countries such as the United States, Canada, France and Spain. Journals with higher impact in the academic community have disseminated the new constructed knowledge. A collaborative network with a few subnets where co-authors are from different countries has been observed. As conclusions, this study allows identifying the themes of debates that mark the development of open access at the international level, and it is possible to state that open access is one of the new emerging and frontier fields of library and information science.
Researchers' Trends, Intentions, and Awareness, Towards Publications in Open Access
Proceedings of the Association for Information Science and Technology
This study examined Israeli researchers' trends, intentions and awareness regarding scientific publications in open access (OA) journals and repositories. A survey was distributed to 202 Israeli researchers. According to the findings, most researchers used a combination of closed (traditional/toll access) journals with OA gold/green routes. Researchers showed low awareness of OA key concepts, which was significantly associated with the tendency not to publish in OA. In addition, researchers who reported that there was a formal policy concerning publishing articles in high-impact journals in their department tended to publish less in OA. The most common reasons that caused researchers not to publish in OA routes were lack of funding and lack of awareness. Conclusions present a need for an OA's declared policy as well as financial and informational support.
