More About the "Pollyanna" Books

There are, so far, 14 or 15 books in the POLLYANNA SERIES, depending on whether or not you include "Six Star Ranch". {I'm going to buy all of the books, and just received "Pollyanna in Hollywood" in today's mail.} Pollyanna doesn't appear in "Six Star Ranch", nor is she so much as mentioned, but the publisher began to list it as part of the series after the publication of the fill-in title, "Pollyanna at Six Star Ranch". This book fills, in part, a gap of 3 or so years in "Pollyanna Grows Up", which I am reading, in part, at this time. In part? Yes, because I'm only reading the first 15 chapters now. When I finish the 15th chapter, I will read "Pollyanna at Six Star Ranch", and then resume "Pollyanna Grows Up". This may seem a bit confusing, but I want to stick, as much as possible, to the chronology of Pollyanna's story.
