It shows research influence and impact at the journal and category levels, and the relationship between citing and cited journals.
What Are Journal Metrics?
Journal metrics measure and often rank the scholarly impact of publications. Journal metrics can play a role in helping you determine where you would like to publish your articles. This page features some key tools for finding journal metrics.
SCImago Journal Rank Indicator (SJR)
The SCImago Journal Rank Indicator (SJR) is also a weighted metric. It was developed from the GooglePageRank algorithm. [2] 
Scopus is the data source for SJR. SCImago includes detailed rankings for journals in the rehabilitation and behavioral sciences.
Find SJR scores on the SCImago Journal and Country Rank website.
Journal Citation Reports & Journal Impact Factor
The Journal Impact Factor (JIF), or impact factor (IF) metric is "the number of cites in the current year to any items published in the journal during the previous two years" divided by "the number of substantive articles (source items) published during the same two years." [1]
The Journal Citation Report (JCR) is an annual report of journals' impact factors. There is also a Five-Year Journal Impact Factor available in JCR from 2007 forward.
Find Journal Impact Factors in BU Libraries' Journal Citation Reports database.
Eigenfactor
Eigenfactor metrics use the data from Journal Citation Reports (JCR), but take five years instead of two years of data for its metrics. It also incorporates disciplinary differences and other factors into its algorithm.
Find Eigenfactor metrics on the Eigenfactor Journal Ranking website or in BU Libraries' Journal Citation Reports database.
