This letter comments on a recent article by Laakso et al. (10.1002/asi.24460), in which the disappearance of 176 open access journals from the Internet is noted. One reason these journals may have vanished is that they were predatory journals: a possibility the original paper did not consider. The delisting 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.

评论“开放并非永远：对消失的开放获取期刊的研究”

这封信评论了 Laakso 等人最近的一篇文章。(10.1002/asi.24460)，其中注意到 176 种开放获取期刊从互联网上消失。这些期刊可能消失的一个原因是它们是掠夺性期刊：原始论文没有考虑到这种可能性。掠夺者于 2014 年从开放获取期刊目录中除名，以及掠夺性期刊在北美的数量及其意识的丰富性，可以简单地解释 Laakso 等人的时间和地理模式。观测到的。
