I have never read the Keith, but there are two contemporary series of time travel stories for young readers that are well into the dozens now -- The Time Warp Trio, and the Magic Treehouse. OF the two, the Time Warp Trio is actually amusing.

I have a vauge memory of these stories. I was a Cub and Boy Scout from 1960 - 66(?) While I didn't read Boy's Life all of those years I am sure I read a couple of these stories. It will be fun to read the whole series over the next couple of weeks.
Thank's

At this point, I've rounded up all 23 stories that I know of, , and written a Wikipedia article about .

I hope this will make the stories findable for those who wish to enjoy them.

I'm years late to this discussion.

I just had a passing memory of these stories as I was reading a review of "The Door into Summer". I had a Boys Life subscription for several years in the 60s, starting well before I actually became a scout. If you read a time machine story in Boys Life, it was one of these.

I came across the same list of Google Books links that was provided twice in this thread, and was surprised and delighted to find out that there were so many more of these stories, and that they were published for a far longer span of time than I would ever have imagined. The few I read probably started with the three part serial from 1965. I may have read them through about 1971.

I just read the first one on my Kindle Fire. I had to zoom the page, which made some of the letters a touch blurred, but it's a short story so it wasn't too rough to read it that way. I'll try the next one out with my iPad to see if it does a better job of holding the resolution as it zooms.
