印刷文章越来越多地依赖在线补充来存储关键的科学信息，但这些数据最终可能无法获得。我们检查了目前在六种被引用最多的科学期刊上发表的在线补充科学信息的可用性（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）。在这里，我们发现，在4.7%和9.6%的文章与在线补充材料，一些补充成为不可用的2年和5年内出版，分别。
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.
