SCImago Journal & Country Rank (SJR)

Unrestricted Access

Description

The SCImago Journal & Country Rank calculates journal influence by looking at both the number of citations received by a journal and the importance of the journal where the citation was published. The SJR indicator is similar to Google Analytic’s PageRank algorithm. This algorithm weights citations from journals according to how highly cited the journal itself is, which differs from the JCR (Journal Citation Reports) which weights all articles identically, regardless of their source. SCImago uses data from SCOPUS, a product similar to the Web of Science, but which covers over 14,000 journal titles.

User tools and features

Searchable categories are arrayed in a frame on the left side of the home page.  Journal search is performed by keying a title into a textbox.  Journal Ranking Parameters may be searched via drop-down menus from the following categories:  Subject Area, Subject Category, Country, and Display Journals with at least __ Citable documents (3 years).  Country Ranking Parameters have a very similar set of categories with drop-down menus:  Subject Area, Subject Category, Region, Order By, and Display Countries with at least __ Documents.  There are also tabs which allow the users to enter multiple values for comparison, as well as a Map Generator, which allows for the generation of maps and bubble charts for visual comparisons.
