ISI have released the most recent data which you can check to find Journal Impact factors.
The Library has a subscription to this and you can access the data on the Web of Knowledge platform. Log in using IP Authentication (on campus only) OR Institutional Authentication (your normal username & password). Choose the tab Select a database and then choose Journal Citation Reports. This is a useful tool to help when deciding where to publish.
If you haven’t used this resource before, there is an online tutorial available or contact the library for assistance.
