Not all databases and indexes offer direct export into EndNote. This tutorial will demonstrate a work around process for PubMed.
Step-by Step:
1. Perform search in PubMed
2. Mark references you wish to export
3. Click SEND TO and select file option - CITATION MANAGER; select number of citations to export, and enter starting number
4. An .nbib file will be exported; and you can choose to Open file in EndNote, where it will save to the IMPORTED REFERENCES group
5. In EndNote, select Imported References, [Ctrl + A] and drag to appropriate group
