最近，互联网使得全球免费获取科学期刊文章成为可能。开放获取 (OA) 可以通过 OA 科学期刊进行，也可以通过作者在开放网络存储库中发布订阅期刊中发表的文章手稿进行。迄今为止，很少有系统的研究表明OA的范围有多大，特别是涵盖所有科学领域的研究。使用 1837 个标题的随机样本和网络搜索引擎研究了在网络上公开全文的同行评审学术期刊文章的比例。 2008 年发表的文章中，8.5% 可在出版商网站上免费获取。另外 11.9% 的免费手稿版本可以通过搜索引擎找到，使得整体 OA 百分比达到 20.4%。化学（13%）的 OA 总体比例最低，地球科学（33%）最高。在医学、生物化学和化学领域，在 OA 期刊上发表论文更为常见。在所有其他领域，作者发布的手稿副本占据主导地位。结果表明，OA 已经对科学期刊文献的可用性产生了显着的积极影响，并且科学学科之间的吸收存在很大差异。由于物理学以外大多数领域的科学家缺乏开放获取出版的意识，因此所有学者都应该对这些结果感兴趣。研究结果也应该引起学术出版商的兴趣，他们需要在其商业战略和版权政策中考虑开放获取，以及研究资助者，如美国国立卫生研究院，他们开始要求开放获取他们资助的研究项目的结果。开发的方法和搜索工具也为更深入的研究和纵向研究提供了良好的基础。
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.
