> Throughout the text, the author provides some impressions of the historical development of logic: Stoic and Aristotelian logic, logic in the Middle Ages and Frege's Begriffsschrift, together with the works of George Boole (1815-1864) and August De Morgan (1806-1871), the origin of modern logic.
Those topics feel pretty typical of logic as studied in philosophy depts. I think traditionally, a lot of logicians working with formal or mathematical logic worked out of philosophy departments. I've been told that more recently, a lot of them now work out of Comp Sci departments. There just isn't enough of them in one place to have a Dept of Logic I guess! :)
"Mathematical Logic" by Roman Kossak is probably mis-categorized. Topics look like typical math topics. Affiliation is Math Dept at CUNY, Bronx Community College campus. Yeah, probably should be under math section.
