This tool lets you compare up to 10 journals using a range of metrics, including SNIP
There’s a couple of ways to proceed now, doing a keyword/subject search to find the top 10 or handpicking your 10 journals
Enter a subject keyword, (optionally) limit to a particular subject area and choose ‘SNIP’ from the dropdown bottom right
Tip: Sopus journals are classified using the ASJC (All Science Journal Classification) scheme. For a complete list of ASJC codes, see All Science Journal Classification Codes (ASJC).
