Journal metrics are used to determine rankings and relevancy of a journal. Information is usually based on citation counts, number of publications and sometimes acceptance rates. There are many places that include journal metrics information, and none of these sources are comprehensive. This guide includes the most common sources for journal ranking and metrics information.
Current (Restricted to ODU)
Journalytics Academic includes a curated list of journals covering 18 disciplines in business, education, health, computer science, psychology and psychiatry, and sciences. Find metrics about where a journal falls within a discipline, acceptance rates, peer review processes, and altmetric attention. Use the Predatory Reports listing to find details about why a particular journal is considered predatory.
Cabell's contains many journals that are not indexed in JCR. Cabell's indicates whether the journal is peer-reviewed, provides acceptance rates, submission guidelines, whether or not the journal is indexed in JCR and/or ERIC, and other editorial information.

About Journal Citation Reports
Impact Factors can be used to:
Things to Know:
Definitions:
Journal Impact Factor: In Journal Citation Reports (JCR), the impact factor measures the importance of a journal by calculating the times its articles are cited. The calculation is based on citations to articles from the most recent two years divided by the total number of articles from the most recent two years.
5-Year Journal Impact Factor: In JCR, citations to articles from the most recent five years are divided by the total number of articles from the most recent five years.
Journal Immediacy Index: In JCR, citations to articles from the current year are divided by the total number of articles from the current year.
Journal Cited Half-Life: The median age of journal articles cited for the current Journal Citation Reports year.
Eigenfactor: Similar to the JCR Five-Year Impact Factor, but weeds out journal self-citations.
Article Influence: The Eigenfactor score is divided by the number of articles published in the journal. Measures the average individual article in the journal (as opposed to the journal as a whole).
Google Metrics assigns an h5-index to journals. The h5-index is based on how many articles that journal has published and how many times articles have been cited. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2 has an h-index of 3. Google Metrics provides a current snapshot of how a journal is doing but not a historical view.
