This is a great question and one that I have been trying to address for my blog. Indeed, information wants to be free and if you look long and hard you can find the article you are looking for in its entirety somewhere out there. I thought about creating a napster-esque website that made the search process easier. Right now that idea is stuck in publisher limbo. The big scientific publishers (LWW, Elsevier) have the market cornered and they know it. I'm not big enough to go in there and pull a Steve Jobs on them. Dunno about you but I'd pay .99 for a full pdf of the article I wanted. They want more like $99, so therein lies the problem.
MD Consult is good for textbooks. If that is the type of reference you are looking for then by all means sign up. My guess is you want the big anesthesia journals. As far as I know there isn't one place to get them all. Abstracts yes, full articles, no. There are some freebies of the new issues but that usually doesn't help a search.
Like everyone else said the best option would be to share an academic username and password. Good for you being all educated in pp!
