You can mark the items you want and use the export feature to copy the citations into your EndNote database.
1. If you have not already done so, create the library (database) in EndNote where you want to import the references.
2. Search the Project MUSE database.
3. Click Save Citation for the references you want to export.
4. Click Saved Citations.
5. Export marked results to EndNote.
The program will take it from there. When finished, check your references to make sure they were imported correctly.
