Is it complete? I have the original DC comics, but would like to have a one-volume copy for easy access. How did they do with the new coloring?
Why wouldn't it be complete?
Like when DC Comics collected the storyline (in 1991), it begins with Spock recovering from Fal Tor Pan and the saga ends with Spock taking up the captaincy of the USS Surak
IDW (2009) uses a different colouring method, which seems to involve a computerized blurring of the "tiny dots" (original grey-screened overlays) in the individual comics. Some panels work better than other. No introduction, either.
IIRC, when DC compiled their own omnibus of the same arc, they recoloured, too, but differently. Some people would recommend checking to see if you can find the DC omnibus instead, and it has a text introduction by A.C. Crispin.
