Snippet: Current project I’m obsessing on (it’s actually really cool and interesting and fun) spans political science, history, philosophy, and even some sociology and criminal justice. So I played all my reindeer games on the journal articles, but when it comes to analyzing the abstracts, a lot were missing. I wanted to ignore these, but they were whole collections from extremely relevant journals and also nearly all of the books. The journals I filled in what i could from Microsoft Academic (no endorsement intended).
Books though…
