One problem with using Web citations is whether those documents will be available over time. We examined 573 Web citations in articles published in nursing journals and checked their availability (either by direct link or by searching the main site). There was a mean of 3.1 Web citations per article. Most Web citations were to documents that related to clinical practice, for example, clinical guidelines and explanations of clinical conditions and treatments. Of the 573 Web citations, 414 (72.3%) were still available; of those, 229 (55.3%) were able to be accessed by direct link and the other 185 (44.7%) by searching the main Web site. However, 159 (27.7%) of the references were not available, not even by searching the Internet using key terms from the citation. Considering that more than a fourth of the Web citations in this study were no longer available, authors need to be cautious about using the Web as a primary source of information for their publications.
使用网络引用的一个问题是这些文档是否能长期可用。我们检查了护理期刊发表文章中的573条网络引用,并核实了它们的可用性(通过直接链接或搜索主网站)。每篇文章平均有3.1条网络引用。大多数网络引用指向的是与临床实践相关的文档,例如临床指南以及临床病症和治疗的解释。在这573条网络引用中,414条(72.3%)仍然可用;其中,229条(55.3%)可通过直接链接访问,另外185条(44.7%)可通过搜索主网站访问。然而,159条(27.7%)参考文献不可用,甚至使用引用中的关键词在互联网上搜索也无法找到。鉴于本研究中超过四分之一的网络引用已不再可用,作者在将网络作为其出版物的主要信息来源时需谨慎。
