There are countless ways Zotero can be put to work at schools or research centers. Students of all stripes, grade school to post-grad, can benefit from Zotero's time-saving organizational features. Teachers can use it as an instructional tool or as part of methods courses. By installing Zotero on every computer, libraries and writing centers can provide their users with the tools necessary to get the most out of their time there. Centers for Teaching Excellence and assessment groups at schools which use Zotero would have a valuable method of gathering data about students' research skills. Of course, these are just a few of the ways Zotero can make a difference at your institution.
Feel free to copy and repurpose any content (text, images, videos, etc.) from the Zotero website to help support and promote Zotero.
The best examples of institution-specific documentation tend to broadly orient users to Zotero, offer institution specific information, and connect users to local workshops, training and basic support. Feel free to point users to Zotero's documentation and forums for advanced use and issues.
Take a look at George Mason University's , Georgia State University's and University of Baltimore's guides for a few examples. The University of Michigan's Zotero Tutorial is also good and quite extensive. More information is available under Third Party Documentation.
