The Find Text button (see below) lets you know whether full text is available. It opens new tab or window, taking you into the library catalog and showing options for accessing the resource under Get It. If one or more links appear under Get It, click any link with the correct date range access the item you want.
If no links appear under Get It and a yellow sign-in bar appears on the record page, log in with your Williams unix credentials and click “Request Scan” to request a copy through interlibrary loan (ILL).
You can also try Googling the citation: sometimes, copyrighted material is freely available on the web. Many journals are free, such as PNAS & PLoS. Some free versions of articles are preprints, with the figures at the end; these are acceptable.
Many of our databases have this button, which searches for the full-text of the article in our collections. If we don't have it electronically, look for the "Request article scan" link in the "Get It" section.
