At the dawn of the Silver Age DC did not go much for crediting the people who created their comics. Even when Marvel arrived and made a point of including credits on all their books, it was a long time before DC followed suit in any formal way, so it can often be difficult to tell who wrote an given comic.
I've been studying the work of three writers in particular, Bob Haney, Bob Kannigher, and Gardner Fox. Although these three share elements of style and content, they can be told apart by their individual approach.
Bob Haney likes to ground his fantastic stories by inserting fashionable touches from the everyday world, but makes no effort to research these elements, and so often gets them wrong, with hilarious results. I particularly like the way the Teen Titans manage to be so popular with all the young people they meet while they are working for the government in the late sixties.
Gardner Fox, on the other hand, is more inclined to throw in some ludicrous plot element and then spend a page justifying it. The more technobabble that he can stuff in there, the better.
But Bob Kanagher. Ah, Bob Kanagher. Big Bob just does mad stuff and feels no need at all to either justify it or make it relevent. Often his work reads like stream of consciousness, where logic is a toy, and Cause and Effect are just the names of the henchmen.
To give you an example how this works in practice, say you have a story where our hero encounters a crashed spaceship.
Gardener Fox would have the spaceship crash and our hero would be led to it by some convoluted plot of the pilot to trap him in another dimension where he would fight dinosaurs, which for some complicated reason would enable the alien pilot to acquire a thermometer, and hthis would include a whole page explaining why the alien pilot couldn't just walk into a shop and buy one.
Bob Haney would have our hero hanging out at a beach party, surfing and riding jetskis up the beach when the spaceship would crash into the car park, cutting all the hot rods off from the main road and making it impossible for the cool kids to get home before curfew without our hero battling the aliens.
Bob Kannagher would just drop the spaceship in front of the hero and have an alien made of flowers jump out and steal his hat, just as a pirate ship arrives, looking for a quiet spot to drop off some foreign saboteurs with a bomb made of cheese.
