Google Scholar supports a feature where many (but not neccesarily all) hits can include a link out to delivery/access services from your particular institution, using an OpenURL link resolver.
This feature keeps getting harder and harder to find though. For links that Google doesn’t believe your institution has fulltext for (sometimes correctly, sometimes not), the link some time ago was relegated behind a “more” popup menu.
If you are using Google Scholar from off-campus (according to IP addresses registered with Google Scholar), you need to set your preferences to select your institution. This keeps getting harder to find too. Recently it changed again — now you only get the “Settings” link on the Google Scholar home page (not on any query results page).
If you are creating web pages for your users and linking to Google Scholar, you may want to use this entirely undocumented and unsupported — but currently still working — trick to automatically set their preference to your institution as part of the URL.
And in general, while I think Google Scholar is a useful tool and I’m glad it’s useful to some users — this reminds us why, having no control over it whatsoever, we can not rely on it as a sustainable solution.
