I have reread many of the Pern books now - am skipping any and all by Todd.
The problem is I can only find
some of the books, the others are somewhere here in my house, but not sure where.

(If I ever win the lottery one of the first things I do will be hiring someone to sort out my books.

).
So for the Pern books I have so far reread:
Dragonflight
Dragonquest
Dragon Song
Dragon Singer
The White Dragon
Dragon Drums
Renegades of Pern
All the Weys of Pernand am in the middle of
The Dolphins of Pern.
(Man, Aramina is the most irritating character McCaffrey ever created. No wonder I never reread Renegades or Dolphins before.

)
I have also found:
Nerilka's Story
Rescue Run
Dragonseye
Masterharper of PernAnd Nerilka must be read with the still MIA Moreta, Rescue Run must be read with MIA Dragon'sDawn, etc. etc.
I will keep looking. In the meantime, I have read the three Crystal Singer books, the five Tower and the Hive books, and the two Brain Ship books which I like best (
The Ship Who Sang and
The Ship Who Searched. If I can find them in my messy multitude of bookshelves, I also want to reread the first Acorna book (like the first better than the others in that series) and the three Petaybe books.
