The points of issue

Is this the true first?
The US Doubleday 1968 hardcover is the true first edition. The UK Macdonald edition (1969) is later.
Telling it from reprints & book-club editions
The Science Fiction Book Club edition lacks the 'First Edition' statement, has the blind-stamp on the rear board with a gutter code, and a club jacket with no printed price.
