E Types

Finally in a position to maybe own one of these to die for cars, but
need to get my feet wet. What is the best all around book about Jaguars
a) in general, esp history of 50s Jags leading up to the E type, and b)
the E type itself. Doesn't have to be repair manual, exploded diagram
type thing at this point, although I might as well hear about those
too. Thanks v much.
