Looking for hay in a hay stack.

Today was about understanding the scope of data in humanities research. With science research, unless you are on the front edge of new and uncharted scientific ingenuity, there are specific data sets that have been made so small that you can see the entire scope easily. Humanities research is instead, a scope that includes human origins and every single act of humans since then. Because no human is an island, our interactions effect the entire world; life in general is one huge butterfly effect. All the data we extract from sources must be equally researched in order to fidn the level or hierarchy of their importance to itinera. This presents the problem that we could go on indefinitely searching, even within the scope of 17th and 18th century Europe. The solution: there's nothing much we can do about that. We still have to take into account all the information and sort it out. We essentially are looking for hay in a hay stack. It's all there, and we must organize them in a way that brings out their optimal relevance.
