A citation analysis of undergraduate term papers in microeconomics revealed a significant decrease in the frequency of scholarly resources cited between 1996 and 1999. Book citations decreased from 30% to 19%, newspaper citations increased from 7% to 19%, and Web citations increased from 9% to 21%. Web citations checked in 2000 revealed that only 18% of URLs cited in 1996 led to the correct Internet document. For 1999 bibliographies, only 55% of URLs led to the correct document. The authors recommend (1) setting stricter guidelines for acceptable citations in course assignments; (2) creating and maintaining scholarly portals for authoritative Web sites with a commitment to long-term access; and (3) continuing to instruct students how to critically evaluate resources.

“…This model, shown in Table 3, identified 17 top-level domains, the number of times a URL has been published, a URL's directory structure depth (hereafter referred to as "depth", using the same definition as [15]), the number of times the publishing article(s) has been cited, whether articles contain funding text as well as 4 journals as having a significant impact on a URL's lifetime at the P< 0.001 level. This survival regression used the logistic distribution and is interpreted similarly to logistic models.…”

BackgroundThe dynamic, decentralized world-wide-web has become an essential part of scientific research and communication. Researchers create thousands of web sites every year to share software, data and services. These valuable resources tend to disappear over time. The problem has been documented in many subject areas. Our goal is to conduct a cross-disciplinary investigation of the problem and test the effectiveness of existing remedies.ResultsWe accessed 14,489 unique web pages found in the abstracts within Thomson Reuters' Web of Science citation index that were published between 1996 and 2010 and found that the median lifespan of these web pages was 9.3 years with 62% of them being archived. Survival analysis and logistic regression were used to find significant predictors of URL lifespan. The availability of a web page is most dependent on the time it is published and the top-level domain names. Similar statistical analysis revealed biases in current solutions: the Internet Archive favors web pages with fewer layers in the Universal Resource Locator (URL) while WebCite is significantly influenced by the source of publication. We also created a prototype for a process to submit web pages to the archives and increased coverage of our list of scientific webpages in the Internet Archive and WebCite by 22% and 255%, respectively.ConclusionOur results show that link decay continues to be a problem across different disciplines and that current solutions for static web pages are helping and can be improved.

This paper presents the results of an investigation into spatial distribution of hyperlinks to the Beijing tourist attractions' official websites. The purpose of this study is to assess whether the hyperlink in the Web could be used to do tourism research. Through this study, the simple inlink count to a tourist attraction's official website was found to highly correlate with the number of the tourist attraction's visitors. This suggests that the inlink count could indicate the attractiveness of a tourist attraction. Further study gives some evidence that spatial distribution of all the inlinks to the Beijing tourist attractions' official websites could reflect the distribution, by country, of the attractiveness of Beijing as a tourist destination.Index Terms-Hyperlink analysis, simple inlink count, spatial distribution of inlinks, the attractiveness of a tourist destination I.
