When using Google Scholar, check the side panel to see if full-text is available. These are more likely to have full access. See the red circles below.
If you find a source you really want to read but do not have access to, please contact your librarian to receive an interlibrary loan. This will take up to 48 hours to receive (and longer if you request on a Friday). Plan ahead if you would like to use a source you do not have access to.
To grab the citation, click "cite" before opening the article. The next screen may not have the citation. Always copy the citation so that you can get back to your source if you lose it.
Or the style your professor requires!
