I wrote "chain complex" in a lot of places where I meant
"cochain complex", like here:

>And, as Simon Willerton pointed out to me, END(I) is a chain complex
>whose homology is familiar: it's the "Hochschild homology" of A.


This should also read "Hochschild cohomology".

Also, here:

>9) Andrei Calderou and Simon Willerton, The Mukai pairing, I:
>a categorical approach, available as arXiv:0707.2052


it should read "Calderaru".

There are probably lots of other mistakes too; I'm fixing them on
the web version, which is here:

By the way, there's a lot of interesting followup discussion going
on here:
