I also just finished reading the two compilations of Mark Evanier's columns which I'd highly recommend to anyone who has any interest in comics. They're great fun and can be read in short sittings. (What do you expect? They're columns! :) )
You can probably order them through his website at http://www.newsfromme.com (which is also worth reading). Right now, he's running a series of articles about the (non-existent) Dick Van Dyke comic book from the early 1960s. It's strange, but fun.
