The best place to start finding peer reviewed articles is Summon (search box on Library homepage - http://libguides.hull.ac.uk/summon). This lets you search all of the electronic journals that the University subscribes to. Once you have run your search, there is an option to limit the search to Peer Reviewed journals.
You will also find peer reviewed journals in the databases that we subscribe to. These can be found in the Finding Articles tab of your subject LibGuide (http://libguides.hull.ac.uk/).
