The number one rule when it comes to picking a topic is this: pick something you are interested in learning more about.
You are going to be spending a lot of time researching your topic, so pick something that you can devote time to without feeling like you are on the rack.

Having the freedom to select ANY TOPIC you want for your paper or presentation is exciting as well as a bit terrifying. (It is, after all, a big world out there with a lot of topics to choose from). So how should you decide on a topic?
Skim over the titles and abstracts of some of your results. How has your topic been studied? Are any of these avenues particularly interesting? Have you noticed any tensions or disagreements among authors writing about your topic?
These questions should help you realize which aspects of your broader topic you are most interested in; this issue can then become your working topic.
Once you have a topic in mind, check out the "Refining your Topic" page of this guide for help structuring your topic and coming up with keywords.

Did your professor give you an assignment with a set, very specific topic? (Be sure you have read your assignment carefully, and understand what you are being asked to do, BEFORE you select a topic and begin researching.)
For example: Explore how Shakespeare creates vivid characters in Othello and discuss how these characters resonate with modern audiences.
Maybe this topic does not sound very interesting to you - or maybe it does - but what I want you take away from this is that YOU have the power to select what ANGLE you take on the topic you have been assigned. And you can select an angle that truly interests you.
Here are some questions I might think about in trying to choose an angle for my Shakespeare paper:
Do you see what we are doing here? We are thinking about our own personal feelings and reactions to the topic we have been assigned. When you hit on an angle that sparks your interest - whether in terms of affection or ire - that is a topic you relate to and would enjoy researching.
