 I guess of the things I've done in the past, the one I'm proudest of and that's most relevant is a companion to Ayn Rand, which is part of the Blackwell Companions to Philosophy series. And it's, I think, the best, the only really reference style work on Ayn Rand's thought, and it covers her philosophy as well as her literature or her views on contemporary political events of her time. And I think is the real step forward in scholarship of her. So the book's pretty expensive. You can get it semi affordably on Kindle, and if, you know, it should be in every library. So if it's not in yours, go complain at them and request it until it gets there.
