In chapter 5 Luker talks about reviewing the literature which basically just goes through how one should go about tracking down sources once he/she dedicates him/herself to a research question. I especially like the tips she includes in this chapter that really come off as a friend telling you exactly what she did and didn't do so that you'll hopefully take that advice and use it to your own benefit.Tips like keeping a search log, and creating your own index seem so obvious, but no one actually tells you to do so, saving you both time and energy. In this chapter I think Luker is so helpful in molding an efficient researcher above anything. The venn daisy (81) for example, is an interesting tool for exploring different aspects of your topic and seeing where they connect when you eventually do the research and aim for specificity.
