ABSTRACT The Internet has recently made possible the free global availability of scientific journal articles. Open Access (OA) can occur either via OA scientific journals, or via authors posting manuscripts of articles published in subscription journals in open web repositories. So far there have been few systematic studies showing how big the extent of OA is, in particular studies covering all fields of science.
The proportion of peer reviewed scholarly journal articles, which are available openly in full text on the web, was studied using a random sample of 1837 titles and a web search engine. Of articles published in 2008, 8.5% were freely available at the publishers' sites. For an additional 11.9% free manuscript versions could be found using search engines, making the overall OA percentage 20.4%. Chemistry (13%) had the lowest overall share of OA, Earth Sciences (33%) the highest. In medicine, biochemistry and chemistry publishing in OA journals was more common. In all other fields author-posted manuscript copies dominated the picture.
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. Due to the lack of awareness of OA-publishing among scientists in most fields outside physics, the results should be of general interest to all scholars. The results should also interest academic publishers, who need to take into account OA in their business strategies and copyright policies, as well as research funders, who like the NIH are starting to require OA availability of results from research projects they fund. The method and search tools developed also offer a good basis for more in-depth studies as well as longitudinal studies.

(2010) studied a random sample of 1,837 articles and searched them using Google. They found out that 8.5% of the articles published in 2008 were available as OA through publishers'websites. "

    ABSTRACT: Google Scholar, a widely used academic search engine, plays a major role in finding free full-text versions of articles. But little is known about the sources of full-text files in Google Scholar. 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 of full-text files. Three queries were created for each of 277 minor subject categories of Scopus. The queries were searched in Google Scholar and the first ten hits for each query were analyzed. Citations and patents were excluded from the results and the time frame was limited to 2004–2014. Results showed that 61.1 % of articles were accessible in full-text in Google Scholar; 80.8 % of full-text articles were publisher versions and 69.2 % of full-text articles were PDF. There was a significant difference between the means of times cited of full text items and non-full-text items. The highest rate of full text availability for articles belonged to life science (66.9 %). Publishers’ websites were the main source of bibliographic information for non-full-text articles. For full-text articles, educational (edu, ac.xx etc.) and org domains were top two sources of full text files. ResearchGate was the top single website providing full-text files (10.5 % of full-text articles).

    ABSTRACT: The present paper aims to investigate the growth and development of knowledge repositories in India, impact of knowledge repository on library staff, infrastructure facilities available in libraries for hosting knowledge repositories and barriers in providing knowledge resources to users through knowledge repositories. Ten KR attached to universities, institutes and other higher learning centres in the country were selected with the help of simple random sampling to conduct the study. The results of the study show that, all the ten libraries under study have instituted publically accessible digital knowledge repositories. Establishment of knowledge repositories has made significant impact on library staff and eight libraries have adequate ICT infrastructure facilities for hosting knowledge repositories with sufficient number of terminals for their users for searching and accessing knowledge resources. Lack of expertise and lack of training is the major barriers faced by 70 percent of librarians, while providing knowledge resources to their users through KR. The paper also puts forward some suggestions derived from the analysis of data for further improvement of the management of knowledge repositories.

This suggestion is sustained on results obtained on recent trends, together with the expected effect of the lasts changes in the journal, especially its open access publication (Björk et al. 2010), that would compensate for the negative effects of the small number of papers published each year and other traits typical from a formerly local journal published by a national society (e.g. Seglen 1997, Leimu and Koricheva 2005).

    ABSTRACT: This paper examines the trends in publication and citation of Galemys, the scientific journal of the Spanish Society of Mammalogist (SECEM) in the last 15 years. We reviewed the citations obtained in the 38 issues of Galemys published between 1997 and 2012 in journals covered by the Journal Citation Reports, as well as in the journal itself. As a whole, 425 articles have been published in Galemys (296 articles and 129 short notes), with an average of 26.5 ± 13.2 (SD) items / year. There have been 596 citations to 408 articles and notes published in Galemys, both in international journals (349 citations, 58.6%) and in the journal itself (247 citations, 41.4%). The average impact of Galemys in the period 1997-2012 was 0.09 citations/year, with a five-years impact factor of 0.15 citations/year, and with a halflife of 7.5 years. Galemys is currently only moderately used by the scientific community, but patterns of use are growing, especially by the Spanish mammalogists linked to the SECEM. Its potential for future use and larger impacts is probably high. This suggestion is sustained on results obtained on recent trends, together with the expected effect of the lasts changes in the journal, especially its open access publication an identification with a DOI and their inclusion in the CrossRef database.
