Journal Impact Factors

If you’re planning to publish an article and want to find out how your chosen journal is ranked against others in the field, there are two sources to look at.  The easiest and most-recognised by publishers is the ‘Impact factor’ from Thomson Reuters.  You can find it through a database called ‘Journal Citation Reports’:
http://libproxy.bath.ac.uk/login?url=http://webofknowledge.com/JCR/
Either ‘View a group of journals by subject category’ or ‘search for a specific journal’
Click the journal title to see how the measures were calculated.

Note that review journals normally score highest, and that you can’t meaningfully compare journals across different subject areas.

There’s a newer alternative measure produced using data from Elsevier’s Scopus database: ‘SCImago Journal Rank’ (SJR)

select ‘journal rankings’ for a list by topic
select ‘journal search’ to find values for a particular journal

Another measure called and ‘Source Normalized Impact per Paper’ (SNIP) allows cross-disciplinary comparison:

You can also view and compare journals’ SJR & SNIP in Scopus:
http://libproxy.bath.ac.uk/login?url=http://www.scopus.com/
Select the ‘Analyze Journals’ option above the search box.

You can find more information about how these are calculated here:
