Source Normalized Impact per Paper (SNIP)

Source Normalized Impact per Paper (SNIP) is a balanced measure for comparing journal citation performance among journals, regardless of the discipline. Created by Henk Moed, SNIP gauges citation impact in a contextual manner by weighting citations based on the total number of citations in a given field. 

- Measures relative citation impact by "normalizing" citation values
- Accounts for a research field’s citation frequency
- Takes immediacy, or how quickly a paper is likely to have an impact in a given field, into account 
- Reduces editorial manipulation of self-citations
