I am wanting to know if anybody has some good research sites to go to. I need to find three research studies that are similiar and print them out for class. I would like to find some studies on trauma or flight nursing since this is where my interest lies. The only problem I am having is I find a good article and I either have to subscribe to the journal or pay a fee. I would like to avoid that if possible. So if anyone has some sites that are reliable and have full text articles for free let me know.
