E Pocrates is free, unless you purchase the "professional" version which offers a few fancy features and adds alternative meds to the program. It's a great program though, I love their multi-drug check program. I have the practical guide to the medical patient by Ferri, and overall, I use it about as often as I use my Washington Manual. Both books are not comprehensive, the Washington Manual discusses a little bit more of pathogenesis and research in it; but each book ends up covering some diseases that the other one does not. Overall, I'd say that it's definitely a book worth having, it has a lot of useful sections in it. It's slightly smaller then the Washington Manual too, which means that it's less likely to rip your white coat pocket and weigh down your coat as much as the manual does. Regarding the intern survival "pocket" books, I would look for drug reps to get these. You should be able to get Sanford, Pharmacopia, intern survival manual, and the critical care survival manual if you are nice to the drug reps. I like to ask drug reps if they have any free books too, because sometimes they do but don't offer them to you when you first meet them.
