Source Normalized Impact per Paper (SNIP) is a bibliometric indicator developed to measure the citation impact of scientific journals by accounting for differences in citation practices across research disciplines. It normalizes raw citation counts based on the contextual citation potential of a journal's subject field, enabling fairer comparisons between journals with different fields and citation behaviors.
