Here
are some brief definitions for the data on the Full Record page.
More complete details can be found in JCR and in Help.
Total
Cites: The total number of times that
the journal has been cited by all journals included in the ISI database
within the current product year.
Impact
Factor: The measure of the frequency with which the "average
article" in a journal has been cited in a particular year. The impact
factor will help you evaluate a journal’s relative importance, especially
when you compare it to others in the same field. It is calculated
by dividing the number of current citations to articles published
in the two previous years by the total number of articles published
in the two previous years.
Immediacy
Index: The measure of how quickly the "average article" in a
journal is cited. The Immediacy Index will tell you
how often articles published in a journal are cited within the same
year. 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.
Articles:
The number of articles published in each journal in the current
product year.
Cited
Half-Life: The number of publication years from the current
year which account for 50% of current citations received. This figure
helps you evaluate the age of the majority of cited articles published
in a journal.
Citing
Half-Life: The number of publication years from the current
year that account for 50% of the current citations published
by a journal in its article references. This figure helps you evaluate
the age of the majority of articles referenced by a journal.
Source
Data Table: The number of review
articles versus original research articles published by a particular
journal. This number also includes the number of references cited
by the articles.
