I just recently read "The Broom of the System", and found Boswell's book to be a very clear and cogent description of Wallace's style and meaning. He very understandably explicates the metafictional foundations and philosophical background of Wallace's approach to literature, and he made alot of sense to me, grounding the work in the modernist and postmodernist literary traditions. I am about to read the chapter on "Infinite Jest", which I read a few years back, and I'm sure it will be very insightful. I learned a great deal from Boswell, not only about Wallace, but about reading, writing literature, and thinking in general. Thanks!
