Impact Measures and Published Scholarship - Evansville: SJR & SNIP

What is SJR and SNIP?

SCImago Journal Rank (SJR) Defined

SCImago Journal Rank (SJR) "is a measure of the scientific prestige of scholarly sources.  SJR assigns relative scores to all of the sources in a citation network.  Its methodology is inspired by the Google PageRank algorighm, in that not all citations are equal.  A source transfers its own 'prestige', or status, to another source through the act of citing it.  A citation from a source with a relatively high SJR is worth more than a cittion from a source with a lower SJR." http://www.journalmetrics.com/faq.php

Source Normalized Impact per Paper (SNIP) Defined

"Source Normalized Impact per Paper (SNIP) measures contextual citation impact by weithting citations based on the total number of citations in a submect field.  SNIP is the ratio of a source's average citation count per paper, and the 'citation potential' of its subject field.  It aims to allow direct comparison of sources in different subject fields."  http://www.journalmetrics.com/faq.php
