Locate items in your Zotero library in OhioLINK by clicking the green arrow in the right column and choosing 'Library Lookup'.
The default will search WorldCat, but you can adjust that in the 'Advanced' tab in 'Preferences'. Insert the OhioLINK link resolver in the OpenURL resolver box.
It's easy to add PDFs to your Zotero library and automatically import their citation info.
If Zotero can't find a match on Google Scholar, don't worry -- you can still save the citation from another catalog or article database, then drag the PDF onto the citation to make it an attachment.
Timelines offer a way for you to visualize your items in your collection. Read more about Zotero timelines.
Or, view the Zotero timelines screencast tutorial.
By default, your Zotero library is stored in Firefox on your computer. You can change the location of the library to a portable drive or elsewhere.
