中国科技期刊开放存取出版现状 总被引：33，自引：1，他引：33
基于《2005年版中国科技期刊引证报告》所收录的1608种我国科技期刊,搜索并统计分析了我国科技期刊的开放存取出版(open access publishing,OAP)现状.结果表明:我国OA期刊已具有一定的数量规模(143种),但部分期刊OA出版的持续性较差,且大都为单刊OA,难以形成信息集成的优势;医学、生物学、农业科学和化学领域中OA期刊的数量相对较多,并且,在同领域中OA期刊的引证影响明显高于非OA期刊.认为我国的相关部门不仅要致力于组建稳定可靠的、有较大信息量的OA期刊网站,而且要关注学术论文的开放存档(open archive). 相似文献

This research explores the performance of Asian S&T journals based on the outcomes of various citation indicators. Indexed by Journal Citation Reports – Science Citation Index Expanded (JCR‐SCIE), journals published in China, Japan, India, Singapore, South Korea, and Taiwan between the years 2008 and 2012 are collected and analysed using bibliometrics and statistics methods. Results showed that the mean impact factor (IF) value of the journals from all countries was less than 1.3 throughout the period. Only journals from China and Japan had a mean IF or 5‐year IF (5Y‐IF) value exceeding 1. The self‐cited rate of the journals from South Korea remained the highest among selected countries but showed a declining trend every year. The self‐cited rates among journals from all the six Asian countries did not considerably affect the journals’ IF values. The results revealed that the IF‐based ranking factor (IF‐RF) of Chinese and Japanese journals in various subject fields constantly improved from 2008 to 2012, but this improvement trend was not observed in journals from the other four countries. Overall, the journals from Japan and China demonstrated stronger impacts than those from the other countries. 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

In this paper, we conduct a comparative analysis to examine the characteristics and evolutionary trends of open access (OA) publications in natural and social sciences. We use data recorded by Science Citation Index Expanded, Social Sciences Citation Index, and Journal Citation Reports during 2001–2015 as the main source. We then comparatively analyse the characteristics of natural and social sciences in terms of historical evolution, main contributors, and distribution of OA journals and publications across different languages, disciplines, and impact factor quartiles. Our results suggest that both natural and social sciences experienced dramatic growth of OA journals since 2009, but the share of social science OA journals within journal impact factor quartile 1 is much lower than that of natural sciences. While natural and social sciences share some similarities in OA publishing activities, such as main countries of contribution, they differ greatly in dimensions such as OA ratio across specific disciplines, countries, and publishing languages. We acknowledge that OA publishing offers a level playing field for traditionally disadvantaged languages, countries, and scientific disciplines, but meanwhile, the advancement of high‐quality OA publishing needs more targeted and sophisticated approaches to tackle differences in natural and social sciences. 相似文献

Digital object identifier and its use in core Chinese academic journals: A Chinese perspective 
下载免费PDF全文
下载免费PDF全文 Digital object identifiers (DOIs) are widely used across the world but not very much within China. This paper investigates the current usage of DOIs in China. Using an isometric method, we sampled 238 core Chinese academic journals from the Chinese Science and Technical Journal Citation Reports (2015 version, Core Edition), which includes 2,383 journals in total. According to our investigation, we found that: (1) although 80.25% of journals assign DOIs, 42.41% have only assigned DOIs to articles published after 2010; (2) most journals (89.01%) register DOIs through Institute of Scientific and Technical Information of China; and (3) only 84.82% of journals that register DOIs include them in the articles. This paper looks at the reasons for the limited implementation of DOIs and makes suggestions as to how usage can be expanded in China. 相似文献

The number of open access (OA) journals and their share of all scholarly journals are usually estimated based on indexing in the Directory of Open Access Journals (DOAJ). DOAJ's coverage of OA journals from different regions of the world is, however, far from complete, particularly of journals publishing in languages other than English. Using alternative data sources for identification and manual verification, 437 scholarly OA journals published in the five Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) were identified, and some key characteristics were studied. Of these, only 184 were indexed in DOAJ. A vast majority of the journals was published by scholarly societies or universities. Social sciences and humanities dominated as topics, and few journals charge authors. National or university‐specific OJS portals have played a major role in enabling OA publishing. Around a third of the Nordic scholarly journals are currently OA. 相似文献

Academic libraries should be considered research tools, co‐evolving with technology. The Internet has changed the way science is communicated and hence also the role of libraries. It has made it possible for researchers to provide open access (OA) (i.e. toll‐free, full‐text, online access, web‐wide) to their peer‐reviewed journal articles in two different ways: (i) by publishing in them in OA journals, and (ii) by publishing them in non‐OA journals but also self‐archiving them in their institutional OA archives. Librarians are researchers' best allies in both of these strategies. Examples of these strategies are described. We conclude that an official mandate for OA provision is necessary to accelerate its growth and thereby the growth of research usage and impact worldwide. 相似文献

Learned societies and other non‐profit organizations in New Zealand publish scholarly journals in a number of disciplines, many of them subjects in which New Zealand has a particular economic interest. Although most of the journals are small, a surprising number of them have paid, rather than voluntary academic, editors. Some have launched electronic versions, but only one has experimented with open access (OA). In a number of cases this lack of interest in OA is because the society cannot see a business model that would render the society as a whole economically viable. Some of the smallest journals, published only annually, may have the most assured future because their operation is entirely voluntary. 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

Metrics on open access (OA) availability of content published in scholarly journals (i.e. content licences, copyright ownership, and publisher‐stipulated self‐archiving permissions) are still scarce. This study implements the four core variables of the recently published Open Access Spectrum (OAS) (reader rights, reuse rights, copyright, and author posting rights) to measure the level of openness in all 1,728 Spanish scholarly journals listed in the Spanish national DULCINEA database at the end of 2015. Data exported from the database and used as variables for the analysis were: journal research area, type of publisher, type of access, self‐archiving and reuse policy, and type of Creative Commons (CC) licence used. Out of the total number of journals (1,728), 1,285 (74.5%) published their articles OA immediately after initial publication and thus received the maximum OAS score for reader rights; 37.5% of all journals used CC licences, and 79.5% allowed self‐archiving in some form. In 72% of journals, authors retained or publishers granted broad rights, which included author reuse and authorization rights (for others to reuse), whilst 13.5% did not specify any terms for copyright transfer. Similar studies could be carried out on other countries as this would enable comparisons of the general adoption and form of openness in different parts of the world. 相似文献

Open access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. The lack of clarity of publisher permissions for archiving in OA repositories affects the adoption of the green OA route. This paper explores editorial policies and self‐archiving conditions in 1,615 Spanish scholarly journals. 48% are published by university and research institutions, 25% by associations/societies, and 17% by commercial publishers; social sciences and humanities (SSH) accounted for 67% of the journals (44.5% and 22.5%, respectively) followed by health sciences (20%); 71% offered gratis access immediately after publication, and 11% after an embargo; 31% provided some mention of author rights. Self‐archiving was specifically allowed by 65% of the journals; 52% were classified as ROMEO‐blue, 12% as green and 15% as white, and 21% could not be classified; 21%, mostly in SSH, used some type of Creative Commons license. 相似文献
