Journal Citation Reports

Journal Citation Reports

For decades, the Journal Citation Reports (JCR) has served as a critical piece of journals collection development, characterization,

and evaluation within academic and government libraries worldwide.

Though certainly its most high profile metric, the JCR is not just the Impact Factor.

JCR – Journal Citation Reports

A host of journal information and metrics to assist in collection development, editorial decision-making, manuscript submission, etc…

Where collection development is concerned – this information is to compliment other factors taken into consideration in determining overall journal influence and impact.

Impact Factor is – Transparent, very easy to understand A known, accepted standard. For decades IF has been accepted by both the publishing and library communities.

There is always the opportunity for open dialog with Thomson Reuters regarding the calculation of IF for a particular journal.

Eigenfactor MetricsTM: EigenfactorTM and Article InfluenceTM:To compliment Impact Factor and other JCR metrics by providing a broader perspective on Journal Influence through specific measures now widely accepted by the scholarly community.

These metrics are developed through The Eigenfactor Project™ -- a non-commercial academic research project sponsored by the Bergstrom lab in the Department of Biology at the University of Washington – www.eigenfactor.org

JCR – Journal Citation Reports – Eigenfactor Metrics

EigenfactorTM Score:

• Scholarly references join journals together in a vast network of citations. The Eigenfactor Score algorithm uses the structure of the entire network to evaluate the importance of each journal, cutting across all disciplines. Self-citations are excluded.

• This corresponds to a simple model of research in which readers follow chains of citations as they move from journal to journal.

• Eigenfactor calculations take into consideration a 5-year span of citation activity utilizing data from the Journal Citation Reports.

• Journals are considered to be influential if they are cited often by other influential journals.
