The following post is part of a Seed Pod collaboration about libraries. Seed Pods are a SmallStack community project designed to help smaller publications lift each other up by publishing and cross-promoting around a common theme. We’re helping each other plant the seeds for growth!
I have spent half my life reading and teaching History (at the college level), and I say this so you will know the following information holds weight.
History is distinguished by the overwhelming volume of sources needed to make an article or book legitimate. The more the better is often the strategy. Notable people leave behind the most sources, and this is one major reason why so many books are written about them. In short, we respect the words of famous people more than the unfamous, and so more sources of the former category are preserved.
