The video demonstrates access of an article in the journal title "The Economists' Voice" through the Stanford "SearchWorks" online public access catalog (OPAC). It starts by searching for the title, then selecting the on-line record from the resulting list. From there, there is an option to find full-text versions of articles.
The SearchWorks OPAC at Stanford is integrated with SFX. The SFX search page shows that the journal is available directly from Berkeley Electronic Press through a Stanford subscription, and from the Stanford LOCKSS box. We naturally search for an article using the LOCKSS target, using the the volume, issue, and page (in this case article number) of the article number that we got from a bibliographic reference.
This takes us to the "landing page" for the article that is being served up by the LOCKSS box. The publisher still receives all hits for counting purposes, but the actual content is served from Stanford's LOCKSS box as long as its content is identical to the publishers. The landing page shows the abstract and a link to the article. Selecting the "Download" button downloads the article preserved in Stanford's LOCKSS box.
