Winter 2005 QG Seminar Errata
John Baez
Here's a list of errors we've found in the Winter 2005 Quantum
Gravity Seminar notes.
If you discover any more errors, please let me know, and
we'll eventually try to correct them, or at least add them to
this list.

Week 1, page 5: "Kelley" should be "Kelly".
The coherence laws for categorified rings are discussed in:

G. Kelly, Coherence theorems for lax algebras
and distributive laws, Lecture Notes in Mathematics
420, Springer Verlag, Berlin, 1974, pp. 281375.

Lecture Notes in Mathematics 281, Springer Verlag, Berlin, 1972,
pp. 2972.
