The Leiden Ranking 2011/2012 is a ranking of universities based on\nbibliometric indicators of publication output, citation impact, and scientific\ncollaboration. The ranking includes 500 major universities from 41 different\ncountries. This paper provides an extensive discussion of the Leiden Ranking\n2011/2012. The ranking is compared with other global university rankings, in\nparticular the Academic Ranking of World Universities (commonly known as the\nShanghai Ranking) and the Times Higher Education World University Rankings.\nAlso, a detailed description is offered of the data collection methodology of\nthe Leiden Ranking 2011/2012 and of the indicators used in the ranking. Various\ninnovations in the Leiden Ranking 2011/2012 are presented. These innovations\ninclude (1) an indicator based on counting a university's highly cited\npublications, (2) indicators based on fractional rather than full counting of\ncollaborative publications, (3) the possibility of excluding non-English\nlanguage publications, and (4) the use of stability intervals. Finally, some\ncomments are made on the interpretation of the ranking, and a number of\nlimitations of the ranking are pointed out.\n
