Here, here, and here.
The title to my post here is what they call "self-recommending", and several of his post titles are intriguing as well.
I've only read Micromotives and Macrobehavior of his books (and a couple articles). I've been meaning to read Strategy of Conflict, the other one I own, but I would certainly recommend the former.
I read it my senior year of undergrad or maybe the summer before or after - not for a class, just for fun. The analysis that really struck me was his discussion of segregation in the book. It had a big impact on how I think about racial disparities. That year I had also done an economic sociology readings/independent study type course. One of the sociology professors was trying to design a syllabus, she knew I was like the only sociology/economics double major in the vicinity of Williamsburg, Virginia at that time, and that I had an interest in it, so we did an independent study to work through some material. So I was reading Schelling around the time I was reading Durable Inequality, by Charles Tilly with her - and a lot of other sociological work on institutional racism.
And that's really what Schelling is discussing: institutional racism. "Racism" might be a bad word to use there because it is so laden with meaning in this society, but the concept is pure Schelling (I'm not sure he ever used it, though). The point is that you can have macrobehavior that is racist in that it reinforces disparities withouth having a substantial level of racism at the level of individual behavior. We individualize race relations far too much in this country and ignore the macroprocesses and the institutions that govern most racial disparities.
I also read Schelling shortly before I gave Keynes my first good cover-to-cover read (practically on a whim... that turne out to be a good whim for me). Just as Gene connects Schelling to Keynes in the third link, I remember thinking back to Schelling a lot as I worked through the General Theory. If you follow me on Twitter (@D_Kuehn), you would have already known I thought this connection was important:
