Another option to use to attach pdfs to citations in your EndNote library, is the Find Full text feature.
To improve your Find full text results, you can add these URLs in EndNote.
Go to Edit >> Preferences >> Find full text.
- In the Open URL path, copy and paste this URL: http://pq7hv8wc2f.search.serialssolutions.com/
- In the Authenticate with: http://ezproxy.waikato.ac.nz/login?url=
To search and download pdfs, highlight the reference(s) you want, then right-click and select Find full text.
It works best on citations that have a doi.
