Printed articles increasingly rely on online supplements to store critical scientific information, but such data may eventually become unavailable. We checked the current availability of online supplementary scientific information published in six top-cited scientific journals (Science, Nature, Cell, New England Journal of Medicine, Lancet, Proceedings of the National Academy of Sciences USA). Here we show that in 4.7% and 9.6% of articles with online supplementary material, some of the supplements became unavailable within 2 and 5 years of their publication, respectively.
印刷版文章越来越依赖在线补充材料来存储关键的科学信息，但这些数据最终可能会变得无法获取。我们检查了六种高引用科学期刊（《科学》《自然》《细胞》《新英格兰医学杂志》《柳叶刀》《美国国家科学院院刊》）上发表的在线补充科学信息的当前可用性。我们发现，在有在线补充材料的文章中，分别有4.7%和9.6%的补充材料在发表后的2年和5年内变得无法获取。
