Your final thesis can be annotated in preparation for your viva. While you might naturally be drawn to underlining typos or adding a few helpful words to the margins, paying attention to the references you cite can be a simple way to improve your thesis’ usefulness as a resource in the viva.
You could highlight different kinds of reference – information, methodology support, question and so on – in different ink colours to draw distinctions between them. You could find the ten most important ones and add highlighter tabs or bookmarks to draw attention to where you use them. You could write a sentence or two at the top of the page to catch your eye.
You had to pay a lot of attention to the work of other researchers to help your research grow. You had to invest a lot if time in being certain that you understood their work and how to apply it to yours. Now, as you prepare for your viva, take a little more time to consider which of these references has been most helpful to you – and find a good way to mark this out in your thesis.
