The disciplines of references and co-authors from five information science journals were analysed. Furthermore, Brillouin\u2019s Index was adopted to measure the degree of interdisciplinarity. The study revealed that information science researchers have cited the publications of library and information science (LIS) most frequently. The co-authors of information science articles are also primarily from the discipline of LIS, but the percentage of references to LIS is much higher. This indicates that information science researchers mainly rely on publications in LIS, and they often produce scientific papers with researchers from LIS. The discipline rankings generated by direct citation and co-authorship show a significant consistency via Spearman\u2019s correlation coefficient test. The interdisciplinary degree of information science has displayed growth. In particular, the degree of interdisciplinarity for co-authors has grown.<\/jats:p>","DOI":"10.1177\/0165551511407141","type":"journal-article","created":{"date-parts":[[2011,5,16]],"date-time":"2011-05-16T23:39:41Z","timestamp":1305589181000},"page":"369-378","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":59,"title":["A study of interdisciplinarity in information science: using direct citation and co-authorship analysis"],"prefix":"10.1177","volume":"37","author":[{"given":"Mu-Hsuan","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Library and Information Science, National Taiwan University, ROC"}]},{"given":"Yu-Wei","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Library and Information Science, Fu Jen Catholic University, ROC,"}]}],"member":"179","published-online":{"date-parts":[[2011,5,16]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1002\/asi.5090190103"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1007\/s11192-007-2002-7"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1002\/asi.4630320302"},{"key":"atypb4","first-page":"327","volume":"49","author":"White HD","year":"1998","journal-title":"Journal of the American Society for Information Science"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4573(81)90040-6"},{"key":"atypb6","volume-title":"The evolution of the interdisciplinarity of information science: a bibliometric study","author":"Al-Sabbagh IA","year":"1987"},{"key":"atypb7","first-page":"121","volume":"13","author":"Tsay MY","year":"2008","journal-title":"Malaysian Journal of Library & Information Science"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4571(199207)43:6<397::AID-ASI1>3.0.CO;2-M"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/S0740-8188(99)00005-5"},{"key":"atypb10","author":"Chikate RV","year":"2008","journal-title":"Library Philosophy and Practice"},{"key":"atypb11","first-page":"31","volume":"2","author":"Chen KH","year":"2004","journal-title":"Journal of Library and Information Studies"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4571(1999)50:12<1051::AID-ASI2>3.0.CO;2-Z"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4571(1999)50:3<271::AID-ASI10>3.0.CO;2-M"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4571(1999)50:11<994::AID-ASI5>3.0.CO;2-U"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1002\/asi.20929"},{"key":"atypb16","doi-asserted-by":"publisher","DOI":"10.1093\/rev\/2.3.169"},{"key":"atypb17","doi-asserted-by":"publisher","DOI":"10.1016\/j.joi.2008.07.003"},{"key":"atypb18","volume-title":"Science and Engineering Indicators 2008","author":"National Science Board.","year":"2011"},{"key":"atypb19","doi-asserted-by":"publisher","DOI":"10.1016\/j.respol.2005.08.002"},{"key":"atypb20","doi-asserted-by":"publisher","DOI":"10.1007\/s11192-006-0127-8"},{"key":"atypb21","doi-asserted-by":"publisher","DOI":"10.1177\/000312240406900204"}],"container-title":["Journal of Information Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0165551511407141","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0165551511407141","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T23:08:04Z","timestamp":1777504084000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0165551511407141"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,5,16]]},"references-count":21,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2011,8]]}},"alternative-id":["10.1177\/0165551511407141"],"URL":"https:\/\/doi.org\/10.1177\/0165551511407141","relation":{},"ISSN":["0165-5515","1741-6485"],"issn-type":[{"value":"0165-5515","type":"print"},{"value":"1741-6485","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,5,16]]}}}
