随着网络文学数量的增加，网络引文在学术出版物中变得普遍。然而，这样的链接不是持久的，许多随着时间的推移而衰败，给读者带来了可访问性问题。本研究调查了三种主要情报学期刊中的链接衰退现象。下载了跨越七年(1997年至2003年)的文章，并摘录了它们的链接。由此计算出链路衰变的半衰期约为五年，与其他学科(1.4至4.8年)相比是有利的。这项研究还调查了遇到的链接可访问性错误的类型，并检查了可能与衰退相关的链接的特征。结果发现，在测试期间，大约31%的引用是不可访问的，大多数错误是由于缺少内容(HTTP错误代码404)。与其他流行的顶级域名相比，来自EDU域名的引文失败率也最高，为36%。结果表明，链接衰减是一个不容忽视的问题，并讨论了对期刊作者和读者的启示。
Web citations have become common in scholarly publications as the amount of online literature increases. Yet, such links are not persistent and many decay over time, causing accessibility problems for readers. The present study investigates the link decay phenomenon in three leading information science journals. Articles spanning a period of seven years (1997 to 2003) were downloaded and their links were extracted. From these, a measure of link decay, the half-life, was computed to be approximately five years which compares favorably against other disciplines (1.4 to 4.8 years). The study also investigated types of link accessibility errors encountered as well as examined characteristics of links that may be associated with decay. It was found that approximately 31% of all citations were not accessible during the time of testing and the majority of errors were due to missing content (HTTP error code 404). Citations from the edu domain were also found to have the highest failure rates of 36% when compared with other popular top-level domains. Results indicate that link decay is a problem that cannot be ignored and implications for journal authors and readers are discussed.
