Journal Citation Reports® Notices

Welcome to Journal Citation Reports®, a unique Web-based research tool that allows you to evaluate and compare journals using citation data drawn from approximately 12,000 scholarly and technical journals and conference proceedings from more than 3,300 publishers in over 60 countries. Journal Citation Reports is the only source of citation data on journals, and includes virtually all specialties in the areas of science, technology, and social sciences.

2012 JCR Data Release

This release of Journal Citation Reports provides 2012 data. The 2013 data will be made available in Journal Citation Reports mid-year 2014.

Journals appearing in JCR

A complete list of the titles covered in this year's JCR is available at: http://scientific.thomsonreuters.com/imgblast/JCRFullCovlist-2013.pdf.

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 2012 JCR. To get information about the new regional content, go to http://isiwebofknowledge.com/products_tools/multidisciplinary/webofscience/contentexp/.


2012 JCR Data Update

After JCR data were published in June 2013, 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 2012 JCR Web data are now complete and all updates have been fully incorporated into the product.

A note on the Mathematics category: the title REP MATH LOGIC appears in the journal summary list for the Mathematics category with a reported Journal Impact Factor of 0.000 placing it as the 296th title in the category as ranked by Journal Impact Factor. Because the denominator of this calculation is zero (no items indexed for the title in 2009 or 2010), no Journal Impact Factor should be reported. The category metrics did not include this journal and report a total of 295 journals in the mathematics category, correctly reflecting the size and content of the category coverage.


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 calculation.
  • 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.

Editorial Information

Title Changes

  • To see a full list of 2010 and 2011 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 2010 or year 2011 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. 

Combined titles

  • 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. 
    • 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

Title Suppressions

Metrics for the titles listed below are not published in the 2012 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. Coverage of these journals in Web of Science and other Thomson Reuters products is not immediately affected by suppression from the JCR, however, the titles may be subject to review to determine if they continue to meet the quality and publication standards necessary for inclusion in Web of Science. More information on journal suppression is available at: http://wokinfo.com/media/pdf/jcr-suppression.pdf
