He implies that such things exist. I think he cites something Turing was supposed to have written (in-universe, I mean) that crossed over between CS and demonology. It doesn't go beyond plausible-sounding titles and breezy one-sentence synopses though.

You can read a bit early on in the first book of the series where he talks a bit about this stuff, on Google books, page 17: https://books.google.ca/books?id=GfSGzhDcU2UC&lpg=PP1&dq=atr...

Stross mentions a suppressed volume of Knuth, can't remember in which book

[EdwardCoffin]

I'd forgotten about that. Stross's book shows its age here, it's volume 4. The bit is on page 134: https://books.google.ca/books?id=GfSGzhDcU2UC&lpg=PP1&dq=atr...
