Published March 26, 2014. DC recalled this edition and will replace it with a new edition in May which will include two additional issues, Detective Comics #768 & Batman: Gotham Knights #29, as well as a revised story order and corrected table of contents.
You may easily identify which edition of the book it is by looking at the back cover copy text. If it lists "Detective Comics 766-770" amongst the reprints you have the corrected printing. If it lists "Detective Comics 766-767 and 769-770" then you have the recalled edition.
