Great index, but, maybe I'm missing something obvious, but I don't get why you don't have links to the other parts of the serials:

Can anyone detail which stories are in which of the two books, MUTINY IN THE TIME MACHINE and THE TIME MACHINE TO THE RESCUE?

The last story I read as a kid was the 1976 "The Time Machine Kidnaps A Parade", so I just now read the final 3 stories.

In "Why We Kidnapped Our Scoutmaster" (February 1989), I point out for the record that, even though they have a time machine, a healing suit, anti-gravity belts, and night goggles, all technology from Kai's time, and the help of an 1851 mountain man, the technology that actually saves Mr. Dunn's life is a 1989 drug dealer's Ferrari car phone!

Incidentally, I just did a similar index of Google Books links to all the SPACE CONQUERORS! space opera serial comics in BOYS' LIFE, 1957-1972, here.
