Two books that I finished recently and highly reccommend are

"To Finish First: My years inside Formula One, Can-Am and Indy 500 racing with Cooper, Brabham and McLaren" by Phil Kerr

"Team Lotus the Indianapolis years" by Andrew Ferguson

I'm glad this got posted again, I'm looking for a few more books to read also. Here's some I've liked.

For history:
"Langhorne!
No Man's Land"
by L. Spencer Riggs

"The Ghosts of Jungle Park "
Second Edition
by Tom W Williams

A good novel to read:
"Return to Glory"
by Greg Littleton

pitstopbooks.com is good to deal with

One of my all time favorites "The Dusty Heroes" by John Sawyer if you can find a copy.
