Ex Libris and Elsevier Collaborate to Harness Journal Metrics for Primo Relevance Ranking

Ex Libris Primo will incorporate SNIP and SNR journal metrics in the ranking of search results

(PresseBox) ( Jerusalem, Israel, )
Elsevier, a leading provider of scientific, technical, and medical information products and services, and Ex Libris® Group, a world leader in the provision of library technology solutions, announced a collaborative initiative to use the source normalized impact per paper (SNIP) and SCImago Journal Rank (SJR) metrics in calculating relevance ranking for Primo search results.

The SNIP indicator takes into account the fact that the frequency of citations varies from one field to another. The SJR indicator combines several factors to produce a measure of the prestige of the citing source. With the new initiative, the SNIP and SJR metrics will be included in the Primo algorithm for calculating the relevance of search results. Also, the display of results will show these metrics to help users assess the scholarly significance of items.

"We are pleased to embark on this additional collaboration with Ex Libris," Cameron Ross, director of product management, A&I databases, commented. "Elsevier is keen to support the academic community by endorsing two independently recognized sources of alternative journal metrics. In the area of journal evaluation, two of the most exciting metrics today are SNIP and SJR. Our goal is to make these measures of impact as widely known and useful to scholars as traditional metrics, and we believe that by incorporating SNIP and SJR into Primo, they will help advance the research endeavor."

David Beychok, vice president of discovery and delivery solutions at Ex Libris, remarked: "Through our longstanding partnership with Elsevier, Primo Central has been indexing the Scopus Abstracting and Indexing database and the full text of ScienceDirect. We are delighted to strengthen our collaboration with Elsevier through our agreement to add SNIP and SJR journal metrics to the other factors in Primo relevance ranking."
