Purpose: There is somewhat of a difference between understanding the open access (OA) concept and practicing it by stakeholders. OA articles are mainly published by gold and hybrid OA journals, but the OA status may be confusing depending on the target databases. This study investigated the OA status of journals and articles and evaluated the extent to which OA2020 (publishing 90% of articles as OA) was achieved.Methods: This study collected OA data by combining 2014-2019 data from Journal Citation Reports at the journal level with Web of Science at the article level. Finally, 12,449 journals were analyzed focusing on gold and hybrid OA journals, and progress towards the goal of OA2020 was evaluated.Results: Even though 80.4% of Journal Citation Reports journals were gold and hybrid OA journals, only 20.9% of the articles were OA (gold OA journals, 16.6%; hybrid journals, 4.3%). The compound annual growth rate of the total articles was 4.7%, that of OA articles was 16.4%, and that of subscription articles was only 1.7%. Among the subscription journals, 77.4% had shifted to become hybrid journals, but only 5.2% of their articles were OA. Therefore, the hybrid journals were at the very early stage of OA publishing.Conclusion: Considerable progress must still be made to achieve the goal of OA2020. The influence of OA publishing will eventually expand and therefore, librarians should take interest in OA publishing for the library services.

Journal Citation Reports 中期刊和文章的开放获取状态

目的：理解开放获取 (OA) 概念与利益相关者实践它之间存在一些差异。OA 文章主要由黄金和混合 OA 期刊发表，但 OA 状态可能会因目标数据库而异。本研究调查了期刊和文章的 OA 状态，并评估了 OA2020（90% 的文章以 OA 的形式发表）的实现程度。方法：本研究通过结合期刊层面的 Journal Citation Reports 中的 2014-2019 年数据收集 OA 数据在文章级别使用 Web of Science。最后，以黄金和混合 OA 期刊为重点对 12,449 种期刊进行了分析，并评估了实现 OA2020 目标的进展情况。结果：尽管 80.4% 的 Journal Citation Reports 期刊是黄金和混合 OA 期刊，但只有 20.9% 的文章是 OA （黄金 OA 期刊，16.6%；混合期刊，4.3%）。总文章年复合增长率为4.7%，OA文章年复合增长率为16.4%，订阅文章年复合增长率仅为1.7%。在订阅期刊中，77.4%的期刊转为混合期刊，但只有5.2%的文章是OA。因此，混合期刊处于OA出版的早期阶段。结论：要实现OA2020的目标，仍需取得较大进展。OA 出版的影响最终会扩大，因此图书馆员应该对图书馆服务的 OA 出版感兴趣。但他们的文章中只有 5.2% 是 OA。因此，混合期刊处于OA出版的早期阶段。结论：要实现OA2020的目标，仍需取得较大进展。OA 出版的影响最终会扩大，因此图书馆员应该对图书馆服务的 OA 出版感兴趣。但他们的文章中只有 5.2% 是 OA。因此，混合期刊处于OA出版的早期阶段。结论：要实现OA2020的目标，仍需取得较大进展。OA 出版的影响最终会扩大，因此图书馆员应该对图书馆服务的 OA 出版感兴趣。
