In a nutshell, you can get around this problem by doing the following:
- If you already have an EndNote library, delete all the terms in your existing journals term list in your EndNote library (if you're starting from scratch with a new EndNote library, this step won't be necessary)
- Import the medical journals terms list created by the University of Queensland Library into your EndNote library - this list contains both full journal titles and abbreviated journal titles for over 10 000 journals in biomedicine and health sciences
- Check the EndNote output style you're using and edit it to specify whether you need it to use the full journal title or the abbreviated journal title
