This is the edition I used. It contains an interview with Bradbury that I found interesting and illuminating.
There are probably helpful interpretations of F451 out there, but I did not encounter them—admittedly I did NOT make any attempt at an exhaustive list of sources. If you know of any helpful ones, please let me know.
If you think future literature lectures could do with more summary of the book as a whole at the outset, let me know, and I can add that in next time.
