Thanks! I've been recommended Fabozzi's book before but with the caveat that it was quite dry (one person said that he felt like he now understood what ADD felt like).

I'll have to check out Guide to Mortgage-Backed Securities.

I don't think either of those books is very good, so try to borrow before you buy. The best of a bad bunch is still bad.

I never look at Fabozzi's book these days, but I still break out the Guide to MBS for its appendix on mortgage amortization formulas. That's a pretty weak recommendation.
