i too have this book but the mere size of it makes me crap...i have whizzed thru it one time and it seems too detailed...but if you are taking the course along with it then it might be ok...as far as the boards, i would also go with the HY series
This is such a low yield topic that I wouldn't even waste time studying it. I would look over FA for it. If you really do feel like preparing for this - HY histo or BRS cell biology are good enough. Just look at the big topics in there, don't waste time with little stuff. http://www.gotmedbooks.com has those listed and some other ones listed under micro/histo if you want to take a look to see what else is available. But I would say spend your time learning something more high yield.
