Journal Citation Reports® Notices
Welcome to Journal Citation Reports®,
a unique Web-based research tool that allows you to evaluate and
journals using citation data drawn from approximately 12,000
technical journals and conference proceedings from more than 3,300
in over 60 countries. Journal Citation Reports is the only
citation data on journals, and includes virtually all specialties in
areas of science, technology, and social sciences.
2011 JCR Data
This release of Journal Citation Reports provides 2011 data.
The 2012 edition of Journal Citation Reports will be made
available mid-year 2013.
Regional Content Expansion
Throughout the years 2007-2009, more than 1,600 journals that focus on
topics of regional interest were added to Web of Science.
Data used to calculate JCR metrics include citations from these
journals as each was included in our citation indexes. Most of these titles are now included in the list
of titles available in the 2011 JCR. To get information about the
new regional content in JCR, go to http://isiwebofknowledge.com/products_tools/multidisciplinary/webofscience/contentexp/.
To access the list of titles receiving their first Journal Impact Factor in the 2011 data, go to http://scientific.thomsonreuters.com/imgblast/JCR-newlist-2011.pdf.

2011 JCR Data Update
After JCR data were published in June 2012, we were able to obtain materials whose absence had prevented journals from receiving a Journal Impact Factor, as well as to correct metrics for a small number of journals. The 2011 JCR Web data are now complete and all updates have been fully incorporated into the product.
Expanded Metrics and Features
- 5-Year Journal Impact Factor is the average
number of times articles from a journal published in the past five
years have been cited in the JCR year. For journals in subjects where
citation activity continues to rise through several years, this metric
allows more of their total citation activity to be included in a
critical performance metric.
Eigenfactor® Metrics, comprising the Eigenfactor®
Score and Article Influence® Score, use JCR
citation data to assess the influence of a journal in relation to other
journals. These metrics, based on five years of citation activity,
consider not just the count of citations but the structure of the
citation network. Eigenfactor Metrics are available only for
JCR years 2007 and later.
Journal Self Cites provides analyses of journal
self citations and their contribution to the Journal Impact Factor
- Rank-in-Category reveals the ranking of a
journal in its subject categories based on the Journal Impact Factor.
An accompanying Impact Factor box plot depicts the
distribution of Impact Factors for all journals in a category.
- The 2011 JCR data (Science and Social Sciences editions
combined) contain 45 journals with new titles in 2009 or 2010 resulting from a
publication changing title, merging with another title or splitting
into two or more separate titles.
- To see a full list of 2009 and 2010 title changes:
- From the Welcome page, if you select View a group of
journals…, Search for a specific journal,
or View all journals, the resulting screen will contain
a link to Journal Title Changes that are specific to
the edition and year of the JCR in which you are working.
- In addition, any individual journal record that is
affected by a year 2009 or year 2010 title change will contain a title
changes link in the Full Journal Record in the Journal
Information section. This will note the specific nature of the
change as well as the other title/titles involved.
- The titles listed below are published in individually titled sections. The individual sections are listed in Web of Science according to their unique titles. For the purposes of JCR listing, the sections are combined and the parent title is retained with a single Journal Impact Factor that combines item counts and citation data for all sections. The decision to combine sections to a single JCR listing is based on JCR Editors' analysis of citation aggregation effectiveness.
- ENER EDUC SCI TECH-A and ENER EDUC SCI TECH-B are combined to: ENERGY EDUC SCI TECH
- J GEOPHYS RES-ATMOS, J GEOPHYS RES-BIOGEO, J GEOPHYS RES-EARTH, J GEOPHYS RES-OCEANS, J GEOPHYS RES-PLANET, J GEOPHYS RES-SOL EA, and J GEOPHYS RES-SPACE are combined to: J GEOPHYS RES
- TIERAERZTL PRAX G N and TIERAERZTL PRAX K H are combined to TIERAERZTL PRAX
- TISSUE ENG PART B-RE, TISSUE ENG PART C-ME and TISSUE ENG PT A are combined to TISSUE ENG
Metrics for the titles listed below are not published in the 2011 JCR. Suppressed titles were found to have anomalous citation patterns resulting in a significant distortion of the Journal Impact Factor, so that the rank does not accurately reflect the journal’s citation performance in the literature. The Journal Impact Factor provides an important and objective measure of a journal’s contribution to scholarly communication, and its distortion by an excessive concentration of citations is a serious matter. JCR staff will monitor these journals going forward and the titles will be included in a future edition of JCR when the problem of citation concentration has been resolved. In the meantime, coverage of these journals in Web of Science and other Thomson Reuters products is not changed.
