The article discusses the adequacy of using the ERIH lists (the European Reference Index for the Humanities) as a tool for categorizing the scientific units in Poland in 2013. Our study examines the international range of journals in which Polish humanists published their texts in 20092012. We examine the published articles through the category of an evaluated item (the indicator used in the Polish categorization of scientific units). The analyzed journals (N = 4274) were indexed on the C part of the Polish „List of Evaluated Journals” which is based on the ERIH lists. We divide journals into two categories: (1) journals (N = 620) with at least 1 publication taken into account in the categorization (128 Polish journals and 492 published outside of Poland), (2) journals (N = 3654) in which there were no publications from the Polish scientific units and no evaluated items. We found 7724 evaluated items which were attributed to the ERIH lists: 75.18% of these items were connected with articles published in the Polish journals which have a national range; 24.12% of these came from 10 Polish journals. Our findings show that the ERIH lists are not appropriate for assessing the internationalization of publications in the categorization of scientific units.
