Impact Measures & Metrics
Citation Analysis or Citation Tracking, involves identifying articles, books, or other materials that have cited a specific work. Citation analysis allows researchers to see who is citing their work, and is also often used to measure researcher and article impact.
Journal Impact is most commonly assessed using impact factor. A measure of the frequency with which the "average article" in a journal has been cited in a particular year, the impact factor helps researchers evaluate a journal's relative importance, especially when compared to others in the same field. Keep in mind that not all journals are ranked.
Book Impact can include reviews of a book, both scholarly and popular, publisher influence, sales figures (when available), and numbers of libraries that own the title. In some cases, the number of owning libraries is not enough evaluative information but, instead, which specific libraries own the title as well.
Researcher Impact is a measure of author productivity and impact over time.
Social/Cultural Impact is relevant for those who may not necessarily have their creative works cited in scholarly literature. Metrics can include information in news publications, reviews, recordings, screenings, exhibitions, grants awarded, and prizes won -- all indicators of a media creator's impact and influence.
Altmetrics are measures of research impact that supplement citations. They measure the wider, societal impacts of scholarly works by tracking how they are discussed, shared, saved, read, and reused by scholars and the public.
