Follow these steps to use the Unpaywall Extension plugin for finding articles:

1. Search for journal articles as you normally would using Google Scholar or library databases.
    
2. As you browse pages containing articles, Unpaywall will add a "tab" to the right side of your screen (circled in red in the image below) linking directly to PDF files. The tab will appear green if the full text is available. If the full text is not available openly, the tab will be grey.
   
    
3. In cases where a PDF is not available, Unpaywall will not appear. Please use UB Libraries Delivery+ service to request the item. 
    

If you have questions about LibKey Nomad or any other library tools, contact the library at library@buffalo.edu or by contacting your subject librarian directly.
