The open access availability of publications by Catalonia's CERCA research centres was analysed to determine the extent to which authors use open access journals, repositories, social networks and other websites to disseminate their research results. A sample of 3,730 journal articles published by authors from CERCA research centres between 2011 and 2015 and available on Web of Science (out of a total output of 44,423) was analysed to identify how many were available in open access, full-text format. The results revealed that 75,8% of the total (2,828 articles) had at least one version available in open access, but just 52% (1,940 articles) had at least one version available in either journals (whether pure or hybrid open access journals or those with embargo periods) or repositories, a finding that highlights the powerful role played by academic social networks in the sharp increase in open access availability. Of the 2,828 articles for which at least one open access version was found, a total of 9,868 copies were located. With respect to versions, the publisher's final version, i.e. the type formatted for publication by journal publishers, was found in 75,3% of cases. The number of articles published in open access journals (567) was very close to the number of articles published in hybrid journals or journals with embargo periods (624). Only 40,4% of the articles in the sample were located in repositories, being the subject repositories the heaviest used. Fifty percent of the articles (1,881 publications) were posted on academic social networks, the most popular of which were ResearchGate and Academia. According to thematic areas, all six areas (science, life sciences, medical and health sciences, engineering and architecture and humanities) exceeded 70% of articles in open access.
对加泰罗尼亚 CERCA 研究中心出版的文献的开放获取可用性进行了分析，以确定作者在多大程度上使用开放获取期刊、存储库、社交网络和其他网站来传播他们的研究成果。对 2011 年至 2015 年间 CERCA 研究中心作者发表的 3730 篇期刊文章（在总共 44423 篇文章中）进行了分析，以确定有多少以开放获取的全文格式提供。结果显示，75.8%的文章（2828 篇）至少有一种开放获取版本，但只有 52%（1940 篇）至少有一种在期刊（无论是纯开放获取期刊还是混合开放获取期刊或有 embargo 期的期刊）或存储库中提供的版本，这一发现突显了学术社交网络在开放获取可用性急剧增加方面发挥的强大作用。在所找到的 2828 篇至少有一种开放获取版本的文章中，总共找到了 9868 份副本。关于版本，发现出版商的最终版本（即期刊出版商排版用于出版的类型）占 75.3%。开放获取期刊（567 篇）发表的文章数量非常接近混合期刊或有 embargo 期期刊（624 篇）发表的文章数量。样本中只有 40.4%的文章位于存储库中，其中主题存储库使用最多。50%的文章（1881 篇）被发布在学术社交网络上，其中最受欢迎的是 ResearchGate 和 Academia。根据主题领域，所有六个领域（科学、生命科学、医学和健康科学、工程和建筑以及人文科学）的开放获取文章比例都超过了 70%。
