It's been said that Superman's Pal, Jimmy Olsen kept reusing the same story ideas because the audience turnover rate was high. That seems to be the same case here. So many of the stories are about aliens manipulating the heroes, superman losing his powers, Batman gaining super powers, Jekyll and Hyde style villains. The comic book was more frequently than bi-monthly, but less frequently than monthly (August, September, October, December, February, March, May, June, August, September, November, December..),so it seems more like an excuse.
Most of the stories here are by Finger and Sprang, but the creative staff is credited here in chronological order even though Edmond Hamilton wrote only two stories (the first two) and Curt Swan illustrated only the last story and a few of the covers. Coleman takes over with #108 until the end of the volume (except Finger's brief return in #111, which may have been an inventory story, as there is very little continuity here), and things, if anything, get weirder. There isn't much more depth to this material than an episode of Super Friends, and there is less variety than in the previous volume, but it's enjoyable and has its moments (Superman gets an unnamed gremlin-like pet who sacrifices its life to save him; Bat-Mite distinguishes himself from Mr. Myxzptlk by his lack of ill intent for Batman) and they manage to do weird things to Superman with only one use of Red Kryptonite near the end.
DC Silver Age comics were definitely kid stuff at this point. Doom Patrol would change all that.
