A Comparison of Research Output Counting Methods Using a National CRIS – Effects at the Institutional Level

Recent decades have seen a trend towards scientific publications with many authors. There is not an agreed way of coun ting co-authored publications. This research in progress contribution compares the behaviour of four representative methods of counting research outputs. We present differences between those methods of counting evaluated at the level of whole universities, their faculties, or non-university research institutes. Our study uses publication metadata from a national CRIS.
