Zotero allows you to save up to 300 MB -- that goes fast when you're saving PDFs! Don't worry, it's easy to link to full text using the web, Google Scholar, or WKU Libraries from within Zotero.
To link to full text from WKU Libraries, you'll need to configure your preferences:
Under "Advanced" edit the OpenURL Resolver. Paste this in exactly:
Click "OK." Now when you use the "Library Lookup" function it will search WKU Libraries for full text access.
