Thats what I do,get an article thats similar and go find the refs' I also like using google scholar, it will gives you several options of links and if your uni subscribes to the onlines then thats great, I also like using MIDIRS (you have to be subscribed though) and my fave is sciencedirect, as you can search easily throughout various journals for that search term, good luck with it all
