What are citation databases?
Citation databases provide information on:
The 3 citation databases are:
Scopus Uses the following Citation Metrics: SJR, SNIP, IPP, Field-Weighted Citation Impact (in Scival)
SJR SCImago Journal Rank
measures the influence of a journal. It takes into account both the number of citations recieved as well as the importance of the citing journal. It normalises for differences in citation behaviour between subject fields allowing the comparison of journals across different subject areas. more about SJR

Where can SJR be found outside Scopus database?
CiteScore Metrics (new metrics database)
CiteScore calculates the average number of citations received in a calendar year by all items published in that journal in the preceding three years. The calendar year to which a serial title’s issues are assigned is determined by their cover dates, and not the dates that the serial issues were made available online. more about CiteScore
SNIP Source Normalized Impact per Paper
measures contextual citation impact by weighting citations based on the total number of citations in a subject field. more about SNIP
IPP Impact per Publication
measures the ratio of citations per article published in the journal. more about IPP
Field-Weighted Citation Impact in SciVal
indicates how the number of citations received by an entity’s publications compares with the average number of citations received by all other similar publications in the data universe: how do the citations received by this entity’s publications compare with the world average?
Resource: SciVal Metrics Guidebook
SciVal is based on output and usage data from Scopus and ScienceDirect.
For each selected metric in the Benchmarking module, you can choose which types of publications to include in the analysis.
Citation Counts - total citations
Citations per Publications - citations for each output
Field Weighted Citation Impact Metric = # of citations received by a document
FWCI =1 indicates the publications have been cited at world average for similar publications
FWCI >1 above world average for similar publications (e.g. 1.5 indicates outputs have been cited 50% above average)
FWCI <1 below world average for similar publications (e.g. 0.5 indicates outputs have been cited 50% below average)
