hey hey- when I did my epq, google books was my best friend. You bascially type in what you want and go on the previews and BAM sources, also google scholar is pretty good. As well as this, if you have a uni in your town, utilise their library (you can get a refrence only card from most of them) and go there for a full day of reading and note taking. also, keep a log/journal of what you're doing, and make a gantt chart. They love gantt charts. hope this is helpful!
