Ah! Sorry to bother people. What I want is all in Weibel Introduction to Homological Algebra chap X. best, Colin 2011/1/10 Colin McLarty <colin.mclarty@case.edu>:

Are there any good results on when inverting a class of arrows in a locally small category gives a locally small result?

Thanks for whatever help anyone can give,  Colin
