it can be tough, but the first place to start would be in the works of the most recent studies on the topic published for an academic audience. Look for ones that are published by University of _____ Press, and the like. Usually there will be a historiography in the introduction or first chapter. This isn't a universal rule, but it's the quickest way.

Now if you are studying to be a historian, building your own is good practice and a skill you'll need to get down before you get to the postgraduate level. Again, you'd want to start with the most recent academic works published by university presses and the like. Things that are peer-reviewed, and written for an academic audience. See who they keep mentioning, who they keep citing, and note whether it's in agreement, or disagreement. Then trace that back, who are those people citing, who are they discussing, and again their thoughts. What new evidence or approaches are they bringing to the table? Eventually it will become evident who the big dogs are, the most impactful works, study those ones well. Build an annotated bibliography to help keep things sorted (and to remind you of what you've already read and the gist of it) and then once you have that solid foundation it's about then approaching it from the start and showing how the field grew, and changed, over time and what's now missing and how your own research will fit into that gap.
