This bibliometric study quantified the impact of different open access (OA) implementations on the number and subject diversity of citations to articles. The study compared two partial OA journals and found that green (institutional repository) OA articles received up to 106% more citations on average than gold (publisher provided) OA or non-OA articles. OA articles received up to 36% more diverse (interdisciplinary) citations than non-OA articles. This result could inform libraries in their decisions regarding OA, specifically the continued importance of institutional repositories. The results will also assist librarians in educating faculty on the benefits of OA. 相似文献

Using data from Web of Science, this research investigates how physical science researchers funded by the Canadian Institutes of Health Research complied with its open access policy, and compares the citation counts of articles published through gold and green models.It was found that, for articles published between 2008 and 2015, 9% were available through gold open access routes and 13% were available through green routes; most were not openly accessible. Citation rates were comparable for green open access and non-open access articles, but citation rates for gold open access articles were lower. After controlling for publication year, citation rates of gold, green, and non-open access articles were comparable. Among gold open access articles, citation rates were highest for open access journals with article processing charges, but after controlling for publication year, articles published in hybrid journals, followed by those in open access journals with article processing charges, achieved the highest citation rates. Articles published in free open access journals had the lowest citation rates. The results suggest that green open access is the most economical approach to comply with open access policies, and that it provides researchers with at least as much research impact as gold open access. 相似文献

We examine open access to the Spanish scientific literature via investigation of a sample of peer‐reviewed articles in seven subject categories. Of the 28,259 papers published in 2000, 26.89% were freely accessible, with the share varying among disciplines. Articles in the social and behavioral sciences were the most widely available for free. This disciplinary divide applies also to the strategies used to offer open access to documents. In clinical medicine, life sciences, arts and humanities and social sciences open access was mainly based on the publishers' side, while subject‐based repositories were dominant in physical, chemical and earth sciences and deposit on homepages was the preferred strategy in engineering, computing and technology. Institutional and general repositories seem to play a minor role in providing free access to the Spanish peer‐reviewed literature. Papers published in commercial journals are less accessible than those that appear in non‐commercial journals, and we found overlaps in almost 20% of papers deposited. The fastest way to gain open access is to deposit in subject‐based repositories and the longest delays are related to deposits in homepages and especially to institutional repositories. Open access to Spanish peer‐reviewed articles is dominated by the passive mechanism of the “gold route” and the editorial strategy with self‐archiving practices in the minority and directed mainly towards subject‐based repositories and homepage posting of the papers. The results of this study could serve as a reference point for further study on the evolution of open access in Spain. 相似文献

The extent to which scholarly literature can be openly accessed and freely downloaded on the Internet varies greatly depending on the discipline. This article assesses the current state of open access in the fields of business and management. Google was used to search for free versions of articles from a sample of articles published in early 2009 in a broad array of business and management journals. Free versions of 36% of the articles included in this study were identified, available from a wide variety of websites, including repositories, author profile pages, open access journals, and more. 相似文献

The Web impact of open access social science research 总被引：1，自引：0，他引：1
For a long time, Institute for Scientific Information (ISI) journal citations have been widely used for research performance monitoring of the sciences. For the social sciences, however, the Social Sciences Citation Index® (SSCI®) can sometimes be insufficient. Broader types of publications (e.g., books and non-ISI journals) and informal scholarly indicators may also be needed. This article investigates whether the Web can help to fill this gap. The authors analyzed 1530 citations from Google™ to 492 research articles from 44 open access social science journals. The articles were published in 2001 in the fields of education, psychology, sociology, and economics. About 19% of the Web citations represented formal impact equivalent to journal citations, and 11% were more informal indicators of impact. The average was about 3 formal and 2 informal impact citations per article. Although the proportions of formal and informal online impact were similar in sociology, psychology, and education, economics showed six times more formal impact than informal impact. The results suggest that new types of citation information and informal scholarly indictors could be extracted from the Web for the social sciences. Since these form only a small proportion of the Web citations, however, Web citation counts should first be processed to remove irrelevant citations. This can be a time-consuming process unless automated. 相似文献

This study investigates the decay and half-life of online citations cited in four open access journals published between 2000 and 2009. A total of 1158 online citations cited in 1086 research articles published in two science and social science journals spanning a period of 10 years (2000–2009) were extracted. Study found that 24.58% (267 out of 1086) of articles had online citations and these articles contained a substantially very less number of online citations (2.98%) compared to previous study results. 30.56% (26% in Science and 52.73% in Social Science) of online citations were not accessible and remaining 69.44% of online citations were still accessible. The ‘HTTP 404 error message-page not found’ was the overwhelming message encountered and represented 67.79% of all HTTP message. Domains associated with .ac and .net had higher successful access rates while .org and .com/.co had lowest successful access rates. The half-life of online citations was computed to be approximately 11.5 years and 9.07 years in Science and Social science journal articles respectively. 相似文献

Business faculty were surveyed to determine their attitudes toward institutional repositories, disciplinary repositories, and open access journals. The majority of faculty was unaware of institutional repositories at their local institutions. However, approximately one third are using disciplinary repositories and are receiving encouragement from their departments to do so. Likewise, many faculty are unaware of open access journals. Open access journals are seen as lacking prestige and being lower quality publications in the business field due to the lack of prestigious publishers and editors. Many faculty believe their prestige would fall if they published in an open access journal. 相似文献

This article reports on scholarly communication and open access (OA) in Korea. Drawing on a range of databases, articles, and reference sources, it provides unique insights. In contrast to the UK/US model of scholarly communication, in Korea, most scholarly journals are published by discipline‐based scholarly societies and research institutes affiliated to universities. Payment for publication is the norm, and typically features article processing charges and scholarly society membership fees for both OA and toll access (TA) journals. Online access to journals in Korea is provided by commercial vendors who enter into contracts with the scholarly societies for exclusive use. Three online access models apply – TA, gold OA, and dual access – with the use of these models varying between disciplines. In parallel with this access provided by commercial vendors, there are a number of government‐funded open access repositories (OARs) to which university researchers are requested to deposit their research outputs, as well as OARs run by universities and other research institutes. 相似文献

Penetration of Nigerian predatory biomedical open access journals 2007–2012: a bibliometric study 
下载免费PDF全文
下载免费PDF全文 This paper presents the bibliometric characteristics of 32 biomedical open access journals published by Academic Journals and International Research Journals – the two Nigerian publishers in Jeffery Beall's list of 23 predatory open access publishers in 2012. Data about the journals and the authors of their articles were collected from the websites of the publishers, Google Scholar and Web of Science. As at December 2012, the journals had together produced a total of 5,601 papers written by 5,599 authors, and received 12,596 citations. Authors from Asia accounted for 56.79% of the publications; those from Africa wrote 28.35% while Europe contributed 7.78%. Authors from Africa accounted for 18.25% of the citations these journals received, and this is about one‐third the number of citations by authors in Asia (54.62%). At country level, India ranks first in the top 10 citer countries, while Nigeria, the host country of the journals, ranked eighth. More in‐depth studies are required to develop further information about the journals such as how much scientific information the journals contain, as well as the science literacy of the authors and the editorial. 相似文献

This paper examines the characteristics of 462 open access (OA) journals being published in India under the green, gold and hybrid models. The sample of journals was selected from DOAJ, IndianJournal.com and Open J‐Gate. Journal characteristics were measured in terms of growth, subjects, publishers, and citations under each model. While characteristics such as growth, subject, and publisher have been identified by exploring the journal's website only, the citation count of these journals has been calculated by using Google Scholar and the Indian Citation Index. The gold road is now the most popular form of OA publishing in the subcontinent. There is a great variation in the size of OA journals and in their publishers. One publisher has more than 77 journals, but 264 publishers publish a single journal only. Overall, the OA journal landscape is greatly influenced by a few key publishers and journals. While 43% of journals charge publication fees and the fees vary from as low as US$10 to as high as US$400, the highest impact factor of the gold OA journals has been noted as 0.58. The data presented here suggest that publication fees are not a major barrier to authorship within the fields of computer science, pharmacy, and medicine. 相似文献

The individual members of 35 UK learned societies were surveyed on their attitudes to open access (OA); 1,368 responses were received. Most respondents said they knew what OA was, and supported the idea of OA journals. However, although 60% said that they read OA journals and 25% that they published in them, in both cases around one‐third of the journals named were not OA. While many were in favour of increased access through OA journals, concerns were expressed about the cost to authors, possible reduction in quality, and negative impact on existing journals, publishers, and societies. By contrast, less than half knew what self‐archiving was; 36% thought it was a good idea and 50% were unsure. Just under half said they used repositories of self‐archived articles, but 13% of references were not in fact to self‐archiving repositories. 29% said they self‐archived their own articles, but 10% of references were not to publicly accessible sites of any kind. The access and convenience of self‐archiving repositories were seen as positive, but there were concerns about quality control, workload for authors and institutions, chaotic proliferation of versions, and potential damage to existing journals, publishers, and societies. 相似文献

This article presents an overview of open access publishing and open access archiving in France. In natural sciences, most articles are published in international journals; authors must therefore comply with the policies of their publishers, irrespective of their nationality. For humanities and social sciences, where publication tends to be distributed among many small journals, portals have been created to provide electronic publishing, with varied access policies. Open archives repositories have been in existence in France since 2001; from 2006, a proactive policy led the main research agencies and universities to coordinate their actions towards a common archiving platform, HAL (Hyper Articles on Line), operated by CNRS (Centre National pour la Recherche Scientifique), with individual portals, either thematic or institutional. HAL stores now the majority of open access records – presently some 10–15% of French output – and is growing almost exponentially. 相似文献

Many journals post accepted articles online before they are formally published in an issue. Early citation impact evidence for these articles could be helpful for timely research evaluation and to identify potentially important articles that quickly attract many citations. This article investigates whether Microsoft Academic can help with this task. For over 65,000 Scopus in-press articles from 2016 and 2017 across 26 fields, Microsoft Academic found 2–5 times as many citations as Scopus, depending on year and field. From manual checks of 1122 Microsoft Academic citations not found in Scopus, Microsoft Academic’s citation indexing was faster but not much wider than Scopus for journals. It achieved this by associating citations to preprints with their subsequent in-press versions and by extracting citations from in-press articles. In some fields its coverage of scholarly digital libraries, such as arXiv.org, was also an advantage. Thus, Microsoft Academic seems to be a more comprehensive automatic source of citation counts for in-press articles than Scopus. 相似文献

The promotion of scholarly journal articles to journalists and bloggers via the dissemination of press releases generates a positive impact on the number of citations that publicized journal articles receive. Research by John Wiley & Sons, Inc. shows that article‐level publicity efforts and media coverage boosts downloads by an average of 1.8 times and were found to increase citations by as much as 2.0–2.2 times in the articles analyzed in this study. We evaluated scholarly journal articles published in nearly 100 Wiley journals, which were also covered in 296 press releases. The results in this case study suggest a need for greater investment in media support for scholarly journals publishing research that sparks interest to a broad news audience, as it could increase citations. 相似文献

New opportunities presented by technological developments are being realised but more can be achieved in opening access to scientific reports and data. Funding agencies and universities are beginning to realise the benefits from an open access model for the dissemination of research results. European funding agencies and universities are following two strategies towards open access, the deposit of research reports in repositories and the conversion of journals to an open access business model. Various public statements have been made in support of open access, and several organizations-such as JISC in the UK-are undertaking work to assist all stakeholders in scholarly communication in introducing beneficial changes. 相似文献
