Q: I tried running Find Full-text on a few references I know we have full-text access to, but it didn't work. Why?
A: Find Full-text works well, but not perfectly. Reasons why include
Publisher's website does not support or allow this functionality.
Too many users are already in a database with limited access.
Journal handles letters, editorials, & other genres differently, making it difficult for EndNote to find the citation.
Article is buried in a large full-text database that does not allow individual articles to be easily retrieved.
If you have had a few failed attempts at using the Find Full-text on a particular reference, then add the article manually to the reference i.e. download the PDF and attach it to the reference.
