Dunno if this is much use but for something simlar to what you're talking about (totally different topic) I used the following structure. Introduction What it says on the tin, introduce the topic and the reason a lit review is necessary. Justification Again, giving very brief info on the papers you've chosen and why you've chosen them. Why are they relevant? What areas do they look into? Overview Using necessary sub-headings, discuss fairly briefly what is contained within each paper and their conclusions and findings. State any reservations the author has with the work or any issue's you've picked up on but don't go too far. Critical Reflection This is where you can start being critical of the papers, picking up on problems you can see and any discrepancies between the papers. It's about picking holes without being too nasty... I used the same sub-headings as the previous section so that it all kinda relates and flows a bit better. Discussion This is a kind of summary of what you've found out. I basically did a paragraph on each of the papers/topics, indicating the shortcomings of their work but also the positive, useful aspects. Concluding Comments Short and sweet indicating whether you've sussed out what you hoped to in the Introduction... References Finally, you need to list the publications you've cited in the text. Hope that's of some use to you... Dave
