However, there are some characteristic differences between co-citations in scientific literature and co-links in hypertext due to the underlying difference in the motivations for creating citations and links. While citations are created for formal scholarly communication, links are created for a variety of formal as well as informal purposes. We elaborate on these differences, and propose interpretations of a co-citation as an endorsement of a citation, and a co-link as an endorsement of a link. Such an interpretation is useful for focused or topical surfers to follow citations and links that are pertinent to a topic of interest in scientific literature and the web respectively. <\/jats:p>","DOI":"10.1177\/0165551510366078","type":"journal-article","created":{"date-parts":[[2010,4,14]],"date-time":"2010-04-14T01:00:59Z","timestamp":1271206859000},"page":"383-400","source":"Crossref","is-referenced-by-count":5,"title":["Co-citations as citation endorsements and co-links as link endorsements"],"prefix":"10.1177","volume":"36","author":[{"given":"Mandar R.","family":"Mutalikdesai","sequence":"first","affiliation":[{"name":"International Institute of Information Technology, Bangalore, India,"}]},{"given":"Srinath","family":"Srinivasa","sequence":"additional","affiliation":[{"name":"International Institute of Information Technology, Bangalore, India"}]}],"member":"179","published-online":{"date-parts":[[2010,4,13]]},"reference":[{"key":"atypb1","first-page":"119","volume":"24","author":"H.D.
