There is no right way or necessarily wrong way of compiling this information. Some historians will be more methodical than others and each will have their own processes.
This course does not cover how you gather your research materials for that very reason but this section will provide an outline of things that you may wish to consider when beginning a research project. Issues such as considering what type(s) and range(s) of data you will likely gather, and what form that data will take, are important considerations which will have a bearing on how you store that material and analyse it.
As you work your way through this section think about how these issues affect you.
