Types of Journal Metrics

Journal Impact Factor
Citations to articles from the most recent two full years, divided by the total number of articles from the most recent two full years.  "How much is this journal being cited during the most recent two full years?"

5-Year Journal Impact Factor
Citations to articles from the most recent five full years, divided by the total number of articles from the most recent five full years. "How much is this journal being cited during the most recent five full years?"

Journal Immediacy Index
Citations to articles from the current year, divided by the total number of articles from the current year.  "How much is this journal being cited during the current year?"

Journal Cited Half-Life
For the current Journal Citation Reports year, the median age of journal articles cited.  "What is the duration of citation to articles in this journal?"

Eigenfactor
Similar to the 5-Year Journal Impact Factor, but weeds out journal self-citations.  It also, unlike the Journal Citation Reports impact factor, cuts across both the hard sciences and the social sciences.

SJR - SCImage Journal Rank
This metric doesn't consider all citations of equal weight; the prestige of the citing journal is taken into account. SJR measures a journal’s impact by taking the average number of weighted citations received in the selected year by the documents published in the journal in the three previous years.

h5-index
This metric is based on the articles published by a journal over 5 calendar years. h is the largest number of articles that have each been cited h times. A journal with an h5-index of 43 has published, within a 5-year period, 43 articles that each have 43 or more citations.

Journal Metrics

A journal is a publication released periodically which contains articles written by various authors.
