Get a copy of Bate's. Not everything in it is relevant to EMS, but it covers a TON of physical exam techniques not taught in EMT class and almost all of them are things that you can do as an EMT.
Whatever you do, don't go looking for it on the internet for free. It's definitely not available on many torrent sites as a PDF. I also definitely don't have a PDF version that I could send you if you're interested. cough
Link to amazon. you can buy used for for like $70.
My advice would be to study up on physical exam. It's an area most in EMS are not proficient in. You don't have to be a Paramedic to perform a good physical exam.
I really like "Mosby's Guide to Physical Examination" and apparently the 5th edition is available online at Barnes and Nobel for only $1.99?? Can't beat that lol
You could also check out, "Bates' Guide to Physical Examination". Amazon
Just wanted to reply with some links to see if these are the books are referring to.
I found both a standard text and pocket edition of Physical exam techniques by Bates. Is there a significant difference between the two besides size and perhaps less detail in the pocket edition?
For clinical presentation, I found this on amazon.
For Diagnoses and treatment "The Merck Manual" I found this
Couldn't find anything on Harrison's anatomy on amazon. I currently have rapid interpretations of EKG, the latest addition as well.
