You've probably seen the Find it! button that allows you to locate the full text of an article online. Zotero allows you to use the same feature.

To set up Zotero to access the Find it! server, click Edit in the Zotero toolbar and choose Settings  then General and look for the section called Locate.

You can search for University of Arkansas, Fayetteville, under the North America pull-down menu. 

Or, you can enter the link below manually as a custom resolver. 

At the bottom of the preferences window, paste this url into the "Resolver" box:

https://onesearch.uark.edu/openurl/01UARK_INST/01UARK_INST:01UARK?

Then click OK.

Once you have set up your OpenURL resolver, click the Locate arrow (green arrow on the upper right side of the Zotero menu bar) to use the Library Lookup feature.
