do you know a prof? Sometimes profs have subscriptions to these journals also.
the above advice is great. (previous reply). A lot of journals have it online and free, especially if the article is not new. So if you find soemthing that 3-4 months old, you can surely find it online.
Also, my state university has a subscription to most of the online medline journals. if you go to your medical library and sit on their computer, you may be able to get it. You see, most state universities have links to these journal articles and the password is saved as cookies. As a result, you probably own't be able to log in from your home, but you may be able to do it from the Univ.
