Accessing Full‐Text Articles
Avoid clicking on publisher icons unless they explicitly state that they are free or unless you are willing to pay $ 35.00 ‐65.00 dollars per article.

It is likely that your institution’s library has facilitated link‐out in PubMed to link you directly to articles from journals to which they subscribe to.
It is also likely that your institution’s library has an Inter‐Library Loan service that will “borrow” the article you want from another library for you for a small charge (certainly less then $35.00!) or for free.
Contact your librarian and find out what services are available and how to use them.
