Unless a journal is open access, you will not be able to use the links provided directly from the publisher, or any other source found on the web, to obtain the full-text of articles. This is because those links are not customized with the required "fair use" copyright permissions provided through the Libraries' subscriptions to journals and databases [i.e., scholarly search engines].
Signing in before you begin your review of the literature ensures that, when you search any of the Libraries' databases, full-text content that is not directly linked in the database can still be accessed. In these cases, look for the button under the item record. Clicking on this button will take you directly to the article or to the table of contents of the journal issue where the article was published.
Using the LibKey Noman Browser App
LibKey Nomad is a browser extension that facilitates access to the Libraries' full text resources as you find research on the web. LibKey provides easy, one-click access to full text journal articles and other sources linked from websites like PubMed, Wikipedia, and publisher pages. For example, when you land on a journal publisher's website, either from a link embedded in another source or from sources found using a general search engine, Libkey Nomad will authenticate you as a student at USC with the privileges required to access the full text of materials currently provided by the Libraries.
Note that installation does not require you to create an account. For more information about LibKey's usage policy, visit the company's privacy policy page.
