Be aware:
-- Not all journals are available electronically;
-- The years of coverage available electronically varies widely;
-- The number of clicks it takes to get to the actual article varies... from one to ten -- it depends on the publisher/vendor set up.
Be patient, read the screens & follow the cues.
Once you plug in your search terms & get a list of articles, you can start choosing those that best address your topic. You will notice some have clickable links to the full text, noted as PDF Full Text or Linked Full Text or HTML Full Text or some similar wording.
Don't be discouraged if such a link is not visible for a great sounding article! The University Libraries may have the article -- even electronically. Just use the Find This for Me button, and look for clickable link(s) under Get it for Me. Just remember the number of clicks it takes to see the article can vary. Look at the information presented & follow the links. This Find This for Me information will open in a new Tab, so you will be able to get to your original search results. It may only take a couple of clicks from the Find This for Me button, or it may take several (publisher, journal, volume, issue, article, pdf) to be able to start reading the article.
If the Get it for Me option is Request Delivery the link will take you to the Delivery/ Interlibrary Loan login & after you login to your account, the request form will be pre-populated with at least some of the article information. Complete any other information you can & submit your request.
