These documents contribute the JIF calculation numerator (citations for JIF year) and denominator (number of citable items). The tabbed Journal Impact Factor contributing items table displays:Ĭitable items – the full list of documents from the previous two years, their open access status, and their citation count (for the JIF year). Journal Impact Factor data for previous years is only displayed for journals in the Science Citation Index Expanded (SCIE) and the Social Science Citation Index (SSCI). Only one year is being calculated for 2022 these journals will not have trend data to display until the 2023 release in June 2024. The graph can be exported in a PDF format using the export link.īeginning with the 2022 metrics released in June 2023, titles indexed in the Arts & Humanities Citation Index (AHCI) and the Emerging Sources Citation Index (ESCI) will have JIFs calculated. To see the full history of both JIF, JIF Percentile, and category assignment for a journal, click the View all years link. Clicking any category in the legend will change the graph to show data for that category. Hovering over any individual year displays the JIF for that year and the JIF Percentile rank for each category. The current year JIF is highlighted, and represents the value shown above the graph. Prior years are presented in ascending order, from the four years prior to the current JIF year to the current year. Journals with a percentile rank below 25% are in the bottom quartile in that category. The 75th percentile gridline marks the lower boundary of the top quartile journal rank the 50th percentile gridline marks the lower boundary of the second quartile journal rank the 25th percentile gridline marks the lower boundary of the third quartile. The JIF Percentile in Category is represented as line-and-marker graph, and corresponds to the right-hand axis. The JIF trend is represented as a bar graph, and corresponds to the left-hand axis. Hover over any point in the graph to see values. The interactive graph above shows the Journal Impact Factor (JIF) and JIF Percentile Rank for the last five years in category. JIF values that would round down to 0 will be displayed as <0.1 going forward. No change is being made to earlier years. Additionally, all JIF, JIF without self-cites, 5 Year JIF, and Immediacy Index values will be displayed to 1 decimal point from 2022 onwards. This extends to the Arts & Humanities Citation Index (AHCI) and Emerging Sources Citation Index (ESCI) for the first time. Journal Impact Factor (JJIF) Values, Data, and Trendsīeginning with the 2022 metrics, released in 2023, all journals in the Web of Science Core Collection will receive a JIF.
