I've had a passing fascination with McCaffrey's books over the years, even as I never really dabbled in them. (I owned one book, Dragonflight, years ago.) I was always somewhat intimidated by the sheer size and scale of the series, and I was always more interested in SF than I was Fantasy (although now, I realize that that was a bit misguided.) Anne McCaffrey was always an author I was aware of: one of the female authors alongside the Asimovs, Herberts and Heinleins in my high school library.
Yet, in recent years, as I've been researching, I've become aware that McCaffrey has occupied an important role in the genre: she's an extremely successful female author, but she also writes in such a way (and is marketed as such) that she's an excellent gateway into the SF world for a huge range of readers.
- Trillion Year Spree: The History of Science Fiction, Brian Aldiss. Aldiss has some excellent points about McCaffrey's early works in his book, although she's mentioned sparingly.
- Transformations: The Story of the Science Fiction Magazines from 1950-1970, Mike Ashley. Ashley provides some outstanding quotes and background into how McCaffrey got her start in the genre, and especially how she was aided by John W. Campbell Jr.
- Gateways to Forever: The Story of the Science Fiction Magazines from 1970-1980, Mike Ashley. This book follows up with Transformations, but likewise provides some good information on McCaffrey's work.
- Partners in Wonder: Women and the Birth of Science Fiction 1926-1965, Eric Davin. This was a particularly good source, providing some interesting background information that didn't appear anywhere else, but also helped my thinking with how McCaffrey got into writing in the first place, but how she viewed her stories.
- Survey of Science Fiction Literature, vol. 2, William Magill. There's an excellent review and overview of Dragonflight in this volume.
- Dragonholder: The Life and Dreams of Anne McCaffrey, Todd McCaffrey. This was a particularly helpful source, but very poorly laid out and written. It's jumbled, and jumps from point to point, making it difficult to locate the right information.
- The Routledge Companion to Science Fiction, edited by Mark Bould, Andrew M. Butler, Adam Roberts and Sherryl Vint. This text had some good background information.
- ISFDB. As always, this is a particularly helpful site for figuring out when and where stories were published.
