Each journal covered in the Journal Citation Reports has a Journal Profile page providing a comprehensive overview of related information and Key Indicators, allowing users to see multiple years' worth of data in a glance. Information related to the journal's publisher, location, and publication frequency, as well as other criteria relevant are presented at the top of the page beneath the title.
The Journal Profile page also provides access to detailed information about the journal, data, metrics and content underlying the journal’s listing in the JCR. Click here for a quick tour.
The page consists of the following elements:
- Journal Information
- Journal Impact Factor Trend
- Citation Distribution
- Journal Impact Factor Calculation
- JIF contributing items
- Source Data
- Three-year content analysis by Country/region and Organization
- All Years page
The Journal information panel contains basic bibliographic information about the journal, including publisher, ISSN(s), Open access status, language, frequency of publication, and Web of Science Categorization.
The Journal Information panel also contains a link to the multi-year profile grid for the journal where all prior years’ data can be accessed.
Journal Impact Factor Trend
This graph shows the Journal Impact Factor and Percentile Rank in Category for the 5 most recent years.
The JIF trend is represented as a bar graph, and correlates to the left hand axis.
The Percentile Rank in category is represented as line-and-marker graph, and correlates to the right-side axis. Gridlines are shown at 25th percentile, 50th percentile, and 75th percentile, allowing quick visualization of the Quartile rank as well.
Prior years are presented in ascending order, from the 4 years' prior to the current JIF year, through to the current year.
The current year JIF is highlighted, and corresponds to the value shown above the graph. Hovering over any individual year will display that year’s JIF and the percentile rank for each category.
The category legend will default to show only the first category, as listed in the Journal information panel above. To view all categories, past and present, click the “Show all” link. This will include any category that was previously assigned to the journal, but is not represented in the most recent years.
To see the full history of both Journal Impact Factors, Percentile Rank and category assignment, for a journal, click on the Expand Button, then use the “View All Years” link. This will expand the history to the first year the journal appeared in the JCR.
The Citation Distribution shows the frequency with which items published in the year or two years prior were cited in the JCR data year; that is, it shows the components of the calculation of the Journal Impact Factor.
The x axis is standardized to display citation counts from 1 to 50, with an additional group on right hand limit of “>50”. The y-axis shows how many items had the x-value of citations in the JCR data year. All journals are displayed on the same x-axis, allowing easy visual comparison of the “impact profile” of different journals. The y-axis scales to accommodate the difference in size between journals.
“Article Citation Median” shows the median citation count in the JCR year for all items with the document type “Article” and published in the year or two years prior to the JCR data year. These items are counted in the JIF denominator as “citable items.”
“Review Citation Median” shows the median citation count in the JCR year for all items with the document type “Review” and published in the year or two years prior to the JCR data year. These items are also counted in the JIF denominator as “citable items.”
Items included in the “other” category on the graph comprise the non-scholarly materials in the journal, including such things as Editorials, news items, correspondence, corrections, obituaries, etc. These are considered non-scholarly and are not counted as part of the denominator of the JIF, however, they may receive citations. Citations to the non-scholarly content are an important part of how the journal influences the scholarly literature, and are included in the JIF numerator.
Non whole-number medians are rounded up to the next highest whole number value to simplify display.
Expanding the graph provides additional detail, the full legend for the display and popup details for the data. In expanded mode, hovering over any bar in the graph will show a summary display of the document types and counts that are present at the specific level of citation.
Expanded view also shows a count of “Unlinked citations.” The Journal Impact Factor is calculated using all citations that can be aggregated to the journal, whether or not they can be linked to an individual published item in the journal. Different journals will have different proportions of unlinked citations. Well established journals with clear, consistent citation metadata support citing authors in creating accurate, effective citations.
Journal Impact Factor Calculation
This presents the mathematical details of the JIF. It displays the year by year count of citations (numerator) and citable items (denominator) that were used to calculate the JIF as published.
The small arrow along the right side of the JIF calculation panel indicates which part of the calculation is displayed in the adjacent “contributing items” panel. The image here indicates that the denominator items are displayed.
Clicking on either the numerator or denominator will open a modal providing article-level detail on the sources of the number.
JIF includes citations to any content in the journal, from any content in Web of Science Core Collections with the publication year = JCR data year:
- Science Citation Index Expanded
- Social Sciences Citation Index
- Arts & Humanities Citation Index
- Conference Proceedings Citation Index – Science
- Conference Proceedings Citation Index – Social Sciences and Humanities
- Book Citation Index –Sciences
- Book Citation Index – Social Sciences & Humanities
- Emerging Sources Citation Index
JIF Contributing Items
This panel contains two elements:
- Citable items (the JIF denominator)
- Citations in the JCR year (JIF numerator)
JIF contributing items provides full visibility and full transparency to the data that were used to calculate the JIF for the current year.
Citable items: The default view is focused on the JIF denominator, the articles and reviews that are counted as “citable” content. On the journal profile page view, five items are shown, in descending order according to the number of citations they received in the JIF year, that is, according to their contribution to the JIF numerator, in addition to their presence in the JIF denominator. This will correlate to the citation counts displayed in the Citation Distribution graph. Items are linked individually to their current version in Web of Science. These data allow users to understand journal citation performance in the context of article citation performance, and vice versa.
Citations in the JCR year: Clicking “Citations in [JCR data year]” will open a list of the top five journals according to the number of citations they have contributed to the JIF numerator. These data are an extract of the Cited Journal data present in the All Years tab. From either Citable items (numerator), or Citations (denominator), clicking “Show all” will open a modal with the full set of data in a scrolled list.
Citable items – Show all view: the full list of Citable items will display all items included in the JIF denominator, ranked in descending order by their citation contribution to the numerator. Items with zero citations in the JCR year are also displayed. Scroll to the bottom to view. Each item is linked to its current data in Web of Science. Please be aware the JCR is a snapshot of the citation indexes at the time of JCR extraction. Web of Science receives daily updates, as well as ongoing corrections. The current data in Web of Science may show some variance from the data in JCR. The “View in Web of Science” link at the top of the Show All view will open the list of items as a search to the current version of Web of Science, subject to your entitlements. This provides you with full article navigation, metadata, analytics and metrics on this population. You will receive a popup information page alerting you to the possible differences between the fully transparent JIF data and the current data in Web of Science. Large journals may take time to load the View in Web of Science page. The “Export” link will download a csv file with a minimum bibliographic record with Web of Science accession numbers.
Citations – Show all view: A full list of citing publications will display. After a short while, the first publication listed will expand to show the individual items that contained one or more citations to the JIF numerator of the journal on this profile page. Scrolling or other functionality will be slowed until this first expansion occurs. If you click the “+” next to any citing publication, it will expand to show the list of citing items in that publication. All items are presented, ranked in descending order by their citation contribution. Each item is linked to its current data in Web of Science.
The “+” next to any citing article will expand to show the specific reference that was counted in the JIF numerator. Unlinked citations will have some variability in the amount of metadata they present, but all include the version of the cited work, cited volume and cited year that were used to define the relationship to this journal and aggregate this reference into the JIF numerator. “View in WoS” will create a search for all citing items. For numerators in excess of 40,000 citing works, the search will be broken into two or more “sets” that must be called individually. The sets can be combined with a Boolean “or” through Web of Science Search History to allow the full list to be viewed and manipulated. The citing items you see in Web of Science will depend on your institution’s subscriptions. All data used to calculate the JIF are presented in the JCR, whether or not your organization subscribes to the edition, and a non-navigable version of the record can be viewed by clicking on the item in the JCR Show All popup.
This panel contains two elements:
- Citable items (the JIF denominator)
- Citations in the JCR year (JIF numerator)
The Source data panel shows the count of items in the journal that were included in JCR analysis for the current JCR year. The count of “citable” items is linked to a full list of those items, which comprise the denominator of the Immediacy Index. This section of the page provides an additional link to the All Years profile grid for the journal.
Three-year content analysis by Country/region and Organization
The final panel uses JCR year Source data, and the two prior years to develop a picture of the countries, regions and organizations that have published materials in this journal in the past three years. Expanding the window will provide up to 50 rank-order positions for the content contributed. The list can be exported as a csv file.
All Years Page
Each journal covered in the Journal Citation Reports has a page providing a comprehensive overview of related information and Key Indicators, allowing users to see multiple years' worth of data in a glance. Information related to the journal's publisher, location, and publication frequency, as well as other criteria relevant are presented at the top of the page beneath the title.
A journal's Open Access (OA) status is marked by
To navigate back to the Current year journal profile page, click on the grey Incites Journal Citation Reports banner.
Key Indicators for each journal are displayed in the table that greets you on the Journal Profile. Many indicator values can be clicked, and a pop-up window displays the data from which that year's metric was calculated. Additionally, visualizations are also accessible by clicking Graph for any indicator of your choosing. The graph appears directly below the table. Clicking on the hyperlinked year allow you to jump directly to that year's data.
For each year that a journal has been published, the Journal Impact Factor displays as a clickable link.Clicking the link displays a pop-up window that contains the calculations behind the number.
The Journal Impact Factor is calculated by dividing citations to recent items by the number of recent items. For journals published in 2016 or later, the denominator in the calculation, the number of recent items, is a clickable link that displays a list of the recent items.
Also included on the Journal Profile page, located directly below the Key Indicators table are sections for each of the following. Click any topic to see the information behind it:
- Source Data- shows the number of citable items in the JCR year.
- Rank - ranking information by year and Journal Impact Factor Percentile for each category in the JCR in which the journal is included as well as Essential Science Indicators information for Total Citations.
- Cited Journal Data - also includes Journal Cited Half-Life information.
- Citing Journal Data - also includes Journal Citing Half-Life information.
- Box Plot - displays Impact Factor information in box plots for each Subject Category in which the journal is included.
- Journal Relationships - data visualization based around the journal which provides a chord diagram for cited or citing data of the top twenty journals in the parent journal's network.
