This release of Journal Citation Reports provides 2018 data. The 2019 data will be available in the 2020 Journal Citation Reports release.

Journals appearing in JCR

This release also includes three new categories: Quantum Science & Technology, Development Studies, and Regional & Urban Planning.

2018 Data Update

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. These metrics can be considered official JCR data but are provisional until final publication in the reload. 

Users may submit feedback for adjustments to citation and citable item counts. All feedback will be considered and fully investigated. The deadline for submitting feedback for consideration for the reload is August 1, 2019.

April 08, 2019

A new application update was released today with the focus on moving the existing functionality from the "All years" tab to the new JCR profile page (current year tab). To that effect, we have made the following improvements to the new JCR profile page in this release. 

  • Added Cited Journal Data, Citing Journal Data and Metric Trend to the new profile page
  • "Graph" option available for each value in the Key Indicator block. The corresponding values are then reflected under the Metric Trend graph. 

March 22, 2019

We are LIVE with the new URLs below. The legacy Thomson Reuters URL will continue to re-direct to the new Clarivate domain URLs for few more weeks. Please take a moment to update any saved bookmarked links you may have to avoid an interruption in service.

Shibboleth/SAML Customers:

Our customers using Shibboleth/SAML SSO to access InCites B&A, JCR, ESI platform are required to perform mandatory configuration changes in order to continue accessing the platform after March 22. 

New SP metadata is available in this location which includes references to the new urls above.

  • Federation/Customers software that supports only single entity should NOT update the url until the cutover date (March 22). They will have to perform the change on March 22 or later to continue uninterrupted access to the platform.
  • Federations/Customers software that support upload of the complete metadata can perform these configuration change between now and the cutover date (March 22). Such customers will need to download our metadata from the above location and upload it into their software to continue uninterrupted access to the platform.

EZ Proxy customers:

We have worked closely with OCLC to update the EZ Proxy configuration available here to incorporate our new URLs. 

Please ensure these configuration updates are completed at the site by March 22 in order to continue accessing the InCites platform.

If you have any questions, please do not hesitate to contact customer care

2018 JCR RELEASE

This release of Journal Citation Reports provides 2017 data. The 2018 data will be made available in the 2019 Journal Citation Reports release.

December 12, 2018 

A new application update was released today with the focus on moving the existing functionality from the "All years" tab to the new JCR profile page (current year tab). To that effect, we have made the following improvements to the new JCR profile page in this release. 

  • The current view of the JIF contributing items in the profile page lists only 5 citable items and citations. With this release, we have increased this number to 10.
  • The citation distribution tile, per requirement, begins with an x-axis value of 1 times cited.  However, this value is not labeled on the axis, causing some user confusion.  Particularly as the y axis does begin at 0 and is labeled that way. To make it more explicit, we are labeling the X axis with this release.
  • Re-organized the key indicators tile within the new Journal profile page and grouped them accordingly.
  • Added box plot and rank visualizations to the current year Journal profile page

November 29, 2018 - JCR Metrics file available

JCR Metrics Files with the October reload data are now available in the JCR application. JCR subscribers who wish to have these files will need to be entitled (via user name and password).

October 17, 2018 JCR Data update

This release contains an update to the 2017 dataset;  26 journals are added with completed information. The 2017 JCR data (2018 release) is now complete and all updates have been fully incorporated into the product. 

We have made the following improvements to the data and calculations in the JCR journal data. 

  • The Article Citation Median and Review Citation Median metrics on the Citation Distribution graph will now show a value “n/a” if no items of that type were counted in the JIF denominator. This allows you to quickly distinguish between a median of 0 (zero), and an absence of any documents of that type.
  • Cited half-life and Citing half-life are now calculated to their precise values. Historically, the JCR data would calculate and display a cited half-life up to 10.0 years.  If citations to ten prior years did not account for at least 50% of the citations received, the value displayed was “>10.0” indicating that the half-life was more than 10 years.  Now, we have completed the calculation so that the actual median age is shown.  See Cited Journal data, and Citing Journal data for more details about half-life.

These updates affect 2017 and on-going data years.  They will not apply to prior years. 

October 03, 2018

We are continuously working on making JCR even better with every update and with this release, we are introducing some key features:

  • "Printable version" links are now available in the new JCR profile page, allowing users to print the entire page or individual visualizations that could be use as handouts or integrated in your presentations
  • The key indicator metrics currently visible in the legacy profile page is now also visible in the new JCR profile page. This ensures a user doesn't have to move back and forth between the legacy profile page and the new profile page.
  • Items published in the two years prior to the JIF that received no citations are now displayed in full.  These "Uncited items" constitutes a new metric - as well as reinforcing the variable role of "non-citable" content in the determination of Impact. The “0 Times Cited” tile shows a breakdown of the uncited items per article, review and "other"; it is available in the Citation Distribution - Expanded View visualization.

Please review the JCR profile page for detailed updates.

JCR Data Update (September 25, 2017)

After JCR data were published in June 2017, 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 2016 JCR data (2017 release) are now complete and all updates have been fully incorporated into the product.

After 2016 JCR data were reloaded and finalized in September 2017, we became aware of a newly occurring and unanticipated cited work variant for Astronomical Journal, which caused a significant undercounting of citations. The following metrics include all citations associated with the new variant:

ASTRON J 

  • Total citations:                32263

Expanded Metrics and New 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. Available in both the Journal Rankings grid and on Journal Profile Pages.
  • Percentage of Articles in Citable Items gives information on what proportion of a journal’s citable items are Articles vs. Reviews. Available in both the Journal Rankings grid and on Journal Profile Pages.
  • Journal Impact Factor Percentile transforms the rank in category by Journal Impact Factor into a percentile, allowing more meaningful cross-category comparison.

New Features:

  • Open Access Filter and Badge - sort results by Open Access status and immediately identify Open Access journals by the badge on the Journal Profile page. 


  • New Data Downloads - On the journal profile page, users can elect to download the cited and citing data tables in CSV/XLS format. The Journal Relationships visualization is now downloadable in PDF format. 

  • Navigating Year-to-Year in the Journal Profle Page - view data that reflects the year of your choice by clicking the hyperlinked year in the Key Indicators table. 

  • Citable Items Document Page - now features the document type and allows filtering based on document type.
