2016 JCR Release

This release of Journal Citation Reports provides 2015 data. The 2016 data will be made available in the 2017 Journal Citation Reports release.

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-2016.pdf

 

A list of journals receiving their first Impact Factor is available at: http://scientific.thomsonreuters.com/imgblast/JCR-newlist-2016.pdf

 


JCR Data Updates

After the initial annual JCR release is published, this section will be updated biweekly with notes about pending additions or adjustments to the JCR data. All changes will be reflected in the JCR application when the dataset is reloaded and closed later in the year. Citation metrics published in this section can be considered official JCR data.

This is unlikely to change, but should be considered provisional until the data are reloaded later in the year.

Please Note: A technical problem briefly affected display of the Journal Impact Factor for International Journal of Disaster Risk Science. The correct Journal Impact Factor is now displaying in product. Note that updated category rankings and quartile information for this journal will be included in the September reload of the JCR data along with all other pending updates. Please be aware that rankings will shift accordingly for the Geosciences, Multidisciplinary; Meteorology & Atmospheric Sciences; and Water Resources categories.

Expanded Metrics and Features

·         Normalized Eigenfactor® is the Eigenfactor Score normalized, by rescaling the total number of journals in the JCR each year, so that the average journal has a score of 1. Journals can then be compared and influence measured by their score relative to 1.

·         Percentage of Articles in Citable Items gives information on what proportion of a journal’s citable items are Articles vs. Reviews.

·         Journal Impact Factor Percentile transforms the rank in category by Journal Impact Factor into a percentile, allowing more meaningful cross-category comparison.

·         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 2014 and 2015 title changes:

o    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. 

o    In addition, any individual journal record that is affected by a year 2014 or year 2015 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. 

o    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

o    TIERAERZTL PRAX G N and TIERAERZTL PRAX K H are combined to: TIERAERZTL PRAX

o    TISSUE ENG PART B-RE, TISSUE ENG PART C-ME, and TISSUE ENG PT A are combined to: TISSUE ENG

o MMWR-MORBID MORTAL W, MMWR SURVEILL SUMM, and MMWR RECOMM REP are combined to: MMWR-MORBID MORTAL W

Title Suppressions

Metrics for the titles listed below are not published due to anomalous citation patterns found in the 2015 citation data. These patterns result in a significant distortion of the Journal Impact Factor and rank that 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. In the interest of fairness and accuracy for all journals, the distortion of the Journal Impact Factor by an excessive concentration of citations gives rise to the need for suppression. JCR staff will monitor these journals going forward and the titles will be included in a future edition of JCR when the anomalous patterns are 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.

Self Citation Suppressed Titles with Key Data Points*

This table lists the categories for each journal (note that each journal may be included in multiple categories), the percentage of citations in the Journal Impact Factor numerator that are self cites, and the distortion in category rank due to self cites.  The distortion in category rank is based on analysis of all journals in all categories of the JCR ranked both with and without the inclusion of self cites.  Here distortion equals the percentage shift in rank with self cites included versus excluded.
