“开放不是永恒的：消失的开放获取期刊研究”述评
Comment on "Open is not forever: a study of vanished open access journals"
摘要：
我们对Laakso等人（arXiv：2008.11933 [cs.DL]）最近的一篇文章进行了评论，其中指出了176种开放获取期刊从互联网上消失。我们认为，这些期刊消失的一个原因可能是它们是掠夺性的期刊。2014年从开放获取期刊目录中删除的掠夺性期刊，以及北美大量的掠夺性期刊及其意识，粗略地解释了Laakso等人观察到的时间和地理模式。
英文摘要：
We comment on a recent article by Laakso et al. (arXiv:2008.11933 [cs.DL]), in which the disappearance of 176 open access journals from the Internet is noted. We argue that one reason these journals may have vanished is that they were predatory journals. The de-listing of predators from the Directory of Open Access Journals in 2014 and the abundance of predatory journals and awareness thereof in North America parsimoniously explain the temporal and geographic patterns Laakso et al. observed.
