Elsevier’s Scopus Partners With CWTS and SCImago to Offer Multidimensional Evaluation of Research Journals

January 26, 2010

AMSTERDAM, January 26 /PRNewswire-FirstCall/ –

– Metrics to be Powered by Scopus and Freely Available Online

Elsevier, a world-leading publisher of scientific, technical and medical
information products and services, today announced that its flagship product
Scopus has successfully partnered with the Centre for Science and Technology
Studies (CWTS) and the SCImago Research Group, endorsing two complementary
journal metrics, SNIP and SJR. The metrics will be freely available online at
http://www.journalmetrics.com, and integrated into Scopus, allowing
researchers around the world to analyze journals within the abstract and
citation database. The indicators will offer a greater currency and
flexibility in journal performance measurement than any single-metric method
currently available.

SNIP, which stands for Source Normalized Impact per Paper, measures a
journal’s contextual citation impact and was developed by CWTS. It allows
direct comparison of journals in different subject fields, by accounting for
the frequency at which authors cite other papers, the speed of maturation of
citation impact, and the extent to which the database covers the field’s
literature.

SJR stands for SCImago Journal Rank, and was developed by the SCImago
Research Group. It is a measure of the scientific prestige of scholarly
sources: value of weighted citations per document. A journal transfers its
own ‘prestige’, or status, to another through the act of citing it. In
effect, this means that a citation from a source with a relatively high SJR
is worth more than a citation from a source with a lower SJR.

Putting SNIP and SJR side by side and applying them to the breadth and
depth of the Scopus database, which covers the greatest number of journal
titles including local language titles from developed and emerging countries,
the new offering represents the most inclusive bibliometric analytics
available for journals. Their integration helps to meet the evolving needs of
the scientific community by providing current, flexible, transparent data to
empower users to build their own tailored journal ranking systems.

“For many years, the scientific community has called for more accurate
metrics that move beyond standard journal classification,” said Niels
Weertman
, Director Scopus, Performance & Planning and Collaboration Tools for
Elsevier. “We are pleased to have the opportunity to partner with CWTS and
SCImago to power the next level of bibliometric analysis. Bringing a more
nuanced approach, we hope to enhance research performance measurement.”

“It’s long been understood that no single journal metric can
realistically address the needs of the research community,” added Professor

Henk F. Moed, currently a senior staff member with CWTS in the Department of
Social Sciences at Leiden University who will be joining Elsevier as a senior
scientific advisor next month. “Our challenge was to develop a more flexible
system. Matching the strengths and weaknesses of one metric to another
complementary metric, we were able to fill many of the existing analytical
gaps. We hope to further expand the number of metrics working alongside each
other in the future.”

“By aligning our SJR indicator with SNIP and leveraging the coverage
breadth and depth of Scopus, we are confident that the outcome is the most
complete bibliometric analysis available today,” stated Professor Felix de
Moya Anegon
of the Centre for Human and Social Sciences (CCHS) of the Spanish
National Research Council (CSIC) in Madrid and director of SCImago. “We’re
also excited by the new opportunity this creates for community-generated
ranking systems that more closely meet market needs and draw a more accurate
picture of research output.”

The journal metrics will be updated twice annually and made available to
Scopus subscribers at http://www.scopus.com and to non-Scopus users at
http://www.journalmetrics.com free of charge. Additional information on the
SJR and SNIP indicators is available through the following recent
