This document provides information about journal metrics available through Scopus, including the SJR (SCImago Journal Rank), SNIP (Source Normalized Impact per Paper), and IPP (Impact per Publication). It explains that these metrics were developed by external bibliometricians and use data from the Scopus database. It also provides brief explanations of how each metric is calculated and what it measures.

1. Finding Journal metrics
via
Scopus:
SJR (SCIMago Journal Rank) SNIP (Source Normalized Impact per
Paper) IPP (Impact per Publication)

2. Elsevier provides three alternative views of the citation impact a journal
makes by using the following metrics:
•Source Normalized Impact per Paper (SNIP)
•The Impact per Publication (IPP)
•SCImago Journal Rank (SJR)
These metrics have been developed by external bibliometricians and source

drop down menu

8. SCImago journal rank (SJR):
SJR is weighted by the prestige of a journal. Subject
field, quality and reputation of the journal have a
direct effect on the value of a citation. SJR also
normalises for differences in citation behaviour
between subject fields.
Choose the Journals to
compare:
Tick the boxes of the journals
you wish to compare. You can
choose up to 10 titles to
compare.

10. Impact Per Publication
(IPP):
The IPP measures the ratio
of citations in a year (Y) to
scholarly papers published
in the three previous years
(Y-1, Y-2, Y-3) divided by
the number of scholarly
papers published in those
same years.

12. Source Normalized Impact
Per Paper (SNIP):
SNIP measures a source’s
contextual citation impact
by weighting citations
based on the total number
of citations in a subject
field. It helps you make a
direct comparison of
sources in different subject
fields.
