Journal Impact Factor discipline rankings lists all of the journals in a discipline based on their JIF. These rankings are available through Journal Citation Reports.
To find rankings for a discipline from the home page, choose the "Select Category" option on the left, then choose a category to display (as shown), then hit Submit (at the bottom of the page).
Journals can also be search for individually - just choose "Search for a specific journal" from JCR's homepage.
Searching for or clicking on an individual journal name will also display all subject categories that journal is classified under, as seen below.
SJR discipline rankings lists all of the journals in a discipline or subdiscipline based on their SJR. These rankings are available only through SCImago's website, scimagojr.com
To find rankings from the home page, click on "Journal Rankings", then select a Subject Area and/or Subject Category. Make sure it says "Order by: SJR" in the dropdown.
The list will also display the quartile ranking for each journal in the category, or which 25% the journal belongs to. The top 25% of journals in that category will show with a green Q1, then a yellow Q2 for the next 25% of journals, and so forth.
An individual journal title can also be searched for - clicking on an individual journal title will show all of the subject areas/categories it belongs to.
The ranked list from the Subject Category "Library and Information Science" is shown above.
Google Scholar rankings list all of the journals in a discipline or subdiscipline based on the H5-index or H5-median. These rankings are available through Google Scholar Metrics.
To find rankings from the home page, click on one of the categories under "English" (or select another language), then click "Subcategories" for subdisciplines. The default ranking is by H5-index, but can be resorted by H5-median by clicking on the top of the appropriate column.
Google Scholar Metrics can also be searched by keyword, pulling up an informal ranking list of journals with that word in the title. Below is a chart of the first few journals with the word "interdisciplinary" in the title, sorted by H5-index.
