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 3
