The points of issue
Knopf (Borzoi) first edition: quarter-bound in white/cream cloth spine over black boards, with the title in black on the spine and the number embossed on the front panel; black endpapers; Paul Bacon jacket. The first printing has the code 5/69 printed at the bottom of the rear jacket flap, the unclipped 5.95 price on the front flap, and First Edition stated on the copyright page with no later-printing statement. 295 pages.
Is this the true first?
The US Knopf edition (1969) is the true first under Crichton's own name; the UK Jonathan Cape edition is also 1969 but follows. The 5/69 rear-flap code is the critical first-printing tell; later printings lack it or show a different date code.
Telling it from reprints & book-club editions
The book club edition lacks the 5/69 flap code and the jacket price, shows the rear-board blind-stamp gutter dot, and is on lighter/thinner boards. The book club edition is very common and is frequently misrepresented as a first.
