This is a listing of my McCaffrey book collection. I think I have almost all of her books, but I'm still hunting a couple. Each set is listed in publication order, the way Anne McCaffrey suggests they be read. This listing should also help you find any holes in your collection. If you know of other books that I'm missing, please let me know.
