Current State of Scholarly Measure
Well-known Problems with Citation Analysis• Self-citations• Citations added because of pressure by editors• Negative citations• Only about 30% of influences are cited*• “Informal” influence isn’t measured through citations• Secondary sources• Review articles “take” citations away from reviewed
articles• Matthew effect – the rich get richer
* MacRoberts and MacRoberts, 2010
