For some time I’ve suggested that researchers make an edited bibliography as part of their viva prep. If you have 200 references, what are the 20 most important? Make a list and add a few details to each of them: which chapter they’re most important to, why, and so on.
Last month at a workshop in Leeds, a participant gave me a brilliant hack of this idea. Think about the main researchers you’ve included in your bibliography, or who are big names in your field. Make a list and write a couple of sentences for each to summarise their research or opinions. Creating the list helps you to think about your field, and afterwards you have a resource to refer to as you prepare for the viva.
