If you access PubMed via the library website, rather than via a bookmark or a search engine, it will make it much easier to find out if we have full-text access to articles. The link from the library website is authenticated, so once you sign in with your SU username and password, PubMed and other databases will know that you're affiliated with SU.
To begin, click this link to go to PubMed. You can also visit the the SU Library homepage, then click the blue Databases button. The A-Z Databases list will show you all the databases we have access to. To get to PubMed, scroll through the list or click the "P" in the alphabetical list to jump to the P section.
Once you're in PubMed, do your search and click on the article you want. Look for a blue “Find Full-text” button in the upper-right corner of the page:
Click the button. If the article is available to you in full text, it should automatically open. If we don't have access to it, you should see a screen that includes the option to “Request this article through interlibrary loan.”
