When we are at the earliest stages of our research, we don't all the way know what we want to argue, what is ahead of us. So, when we get to the annotated bibliography, we tend to scoop up the required number of sources, annotate them and wait for the next part of the assignment.
In today's session, we will talk a lot about how important and helpful it is to stay focused on a narrow topic when searching for and gathering sources. We will talk about how to collect sources with a planning mindset so that the work you do at this stage will serve you best later on.
Remember that the claims you make in a paper should be in direct proportion to the sources you cite.
