What they, are, though, is a useful measure of journal impact and prestige... so we need to take them into account when considering publishing anything.
JIF - Journal Impact Factor – “measures” how often articles in
journals are cited.
Or, the
average number of citations in that year that a paper published in a particular
journal in the previous two years receives.
E.g. the 2010 IF is the average
number of citations received in 2010 for 2008 and 2009 papers
- JIF can be found using Thomson Reuters Journal Citation Reports
SNIP - Source Normalised Impact per Paper – “measures” contextual citation
impact by weighting citations based on the total number of citations in a
subject field
Citation
potential is shown to vary not only between subject categories or disciplines
but also between different “types” of journals within the same subject category.
E.g.
basic journals vs. applied/clinical journals
- SNIP can be found using Scopus Journal Analyzer
And my personal favourite...
“…based on the transfer
of prestige from
a journal to another
one;
such prestige is transferred
through
the references that a journal do to the rest of the journals and
to itself.”
- SJR can be found using Scopus Journal Analyzer, or going directly to the SCImago journal ranking webpage
