I am looking for a term used to describe how much in detail one is studying a historic event.
For instance, if one studies a college course called "History of the World" in one semester, one gets just surface knowledge of a given event, e.g. the Bolshevik revolution might be described but not in much detail.
On the other hand, if one takes a course called "History of the Bolshevik Revolution" one if going to study much more detail about it.
Furthermore, if one does a PhD, one could pick one tiny aspect of that.
The word "depth" is close, but I am wondering if their is a more scholarly term for this used within history. In other words, one can use "depth" in science to mean how detailed one studies a area of science, but because history is a continuum and is measurable by time, so that actual depth can be studied on a scale, I think the concept of "depth" is special to this study so there might be a unique term applied for use in historical studies.
