Buschman M, Michalek A. Are alternative metrics still alternative? Bulletin of the Association for Information Science and Technology 2013;39(4):35-39
Alternative metrics provide a more complete view of peer response to scholarly writings. A better categorization of scholarly impact would cover usage, captures, mentions and social media in addition to citations. Metrics should include mentions in blogs and other nontraditional formats, open review forums, electronic book downloads, library circulation counts, bookmarks, tweets and more.
