Hi all--mods, please remove if this post is inappropriate, but I'm hoping to get a perspective from as many practising historians as possible and this seems like the place!

I'm an engineering grad student, and I've recently become involved in a project to analyze the economic success or failure of large engineering projects executed by the US government between 1960 and 2010. (I'm being a little vague, as the details of the project would make me pretty immediately identifiable--sorry.) Our focus is primarily on matters of project management, organizational culture, internal project politics, and government agency interactions with Washington politics. The engineering aspects are not very important to this research--it's nearly all historical analysis, with some limited quantitative analysis since the number of relevant cases is quite small.

I've been spending a lot of time reading lengthy, interconnecting documents written by different individuals and organizations, at different times, with varying agendas and access to information. I'm finding myself overwhelmed by all this information, and am struggling to effectively take and organize notes. I use Evernote extensively, but without any particular level of sophistication. Since this is largely an endeavor in historical research, I'm hoping some of the experts on this sub can offer me some recommendations or best practices in your field. Thank you very much in advance!
