Welcome to the next-generation newly "wikified" guide to Thomas Pynchon's Gravity's Rainbow (ISBN: 0140188592). Tim Ware is the curator. If you would like to contribute in any way, please send an email letting us know who you are and what you'd like to do, and we'll set you up so you are authorized to made contributions and edits to these pages. What's missing will eventually be there, although, sure enough, completeness will remain completely out of reach.
Read Professor Irwin Corey's acceptance speech for Pynchon's 1974 National Book Award for Gravity's Rainbow.
Also, have a look at Douglas Kløvedal Lannark's exhaustive documenting of ((love)) in Gravity's Rainbow.
An excellent resource for Gravity's Rainbow is Steve Weisenburger's A Gravity's Rainbow Companion and, of the many excellent books of criticism, you'll find Thomas Moore's The Style of Connectedness: Gravity's Rainbow and Thomas Pynchon and Kathryn Hume's Pynchon's Mythology well worth reading. If you can locate Richard Sasuly's IG Farben, long out of print, you'll find that it fills in much about that monster-concern as his book is considered to have been a major source of the IG-Farben-related information in GR. Enjoy.
The page numbers refer to the original Viking editions (1973), paperback and hardback, and to the Penguin edition (1987). To get the Bantam edition (1974) page numbers, multiply the page numbers by 1.15 for the first third of the book, 1.16 for the second third, and 1.17 for the last third. This is approximate but should work.
