As a consequence, the distributions of the indicators are not comparable across different disciplines. Here we show that the most popular journal citation indicators used in quality assessment \u2014 the journal impact factors of Thomson Scientific and the scientific journal rankings of Scopus \u2014 are strongly correlated with the proportion of within-database references, and even more so with the number of within-database recent references per paper. No significant correlations were found with other bibliometric magnitudes. We anticipate that these results will be a starting point for more sophisticated indicator models that take this dependence into account, and for the design of strategies aimed at extending such bibliometric databases as Thomson Scientific\u2019s Science Citation Index or Elsevier\u2019s Scopus to improve their capacity to evaluate all sciences.<\/jats:p>","DOI":"10.1177\/0165551510366077","type":"journal-article","created":{"date-parts":[[2010,4,13]],"date-time":"2010-04-13T21:00:59Z","timestamp":1271192459000},"page":"371-382","source":"Crossref","is-referenced-by-count":58,"title":["What lies behind the averages and significance of citation indicators in different disciplines?"],"prefix":"10.1177","volume":"36","author":[{"given":"B\u00e1rbara S.","family":"Lancho-Barrantes","sequence":"first","affiliation":[{"name":"Universidad de Extremadura, Grupo Scimago, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vicente P.","family":"Guerrero-Bote","sequence":"additional","affiliation":[{"name":"Universidad de Extremadura, Grupo Scimago, Spain,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e9lix","family":"Moya-Aneg\u00f3n","sequence":"additional","affiliation":[{"name":"CSIC, CCHS, IPP, Grupo Scimago, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2010,4,13]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1002\/asi.4630360402"},{"key":"atypb2","volume-title":"Citation Analysis in Research Evaluation","author":"H.F.
