What other metrics are available for journals in my area?
Alternative metrics:
What do the headings mean?
- Total cites: The number of times journal articles published in 2009 cited articles published in each listed journal.
- 5-year impact factor: this is calculated similarly to the traditional 2-year impact factor but uses a 5-year rather than a 2-year window. A base of five years may be more appropriate for journals in certain fields because the body of citations may not be large enough to make reasonable comparisons, publication schedules may be consistently late, or it may take longer than 2 years to disseminate and respond to published works.
- Immediacy index: the immediacy index tells you how often artiicles published in a journal are cited during their year of publication. This can be an indication of how "hot" a journal is. It is calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year.
- Cited half life: the cited half life for a journal is the median age of its items cited in the current JCR year. Half of the citations to the journal are to items published within the cited half-life.This measures whether citing continues over time for a journal's content.
- Eigenfactor: JCR links to the Eigenfactor metrics
