yep I am going to second all the above. I bought IM On Call for my Palm, which was a COMPLETE waste of money. I never used it. I got a free Wash Manual on my first day complements of a drug rep. I did carry that for a month or two, but used it only once or twice for SBP and acute pancreatitis (ahh, I remember how scared I was of pancreatitis ... before: I remember from my texts, such a serious disease .. now: oh, another pancreatitis ... ok "yawn"). I also have the MGH book which is quite good.
BUT ... in reality all I use now is up to date, I also like the UCSF on-line handbook (but use it only rarely). The above poster was right ... the stuff you don't know and want to look up is damn hard to find! Everything else is too simplistic or too detailed to dig through. Medicine is not that hard. You learn by doing a couple times. Really the only things I still fear are ventillators and pleurocentesis (that needle is SO DAMN LONG!!!). One of our best interns dropped a lung the other day. Any how ....
