I think I read a couple of those, but my library as a kid didn't have the complete series. My favorite series was the Betsy-Tacy books by Maud Hart Lovelace. I ended up collecting all of them in hardbook when I was an adult. The funny thing is that I read Lovelace and Johnston concurrently, but it wasn't until years later that I happened to read the dedication in "The Wishing Star". Johnston dedicated it to Lovelace and called her "my wishing star". I love it when things like that happen. :)
