It is a good idea to regularly back up your EndNote library.
- Open the File Menu and select "Compressed Library."
- Select "Create."
- Navigate to the folder where you will put your backup library, or create a new folder for it.
- You can change the name of the library (mylibrary_backup is a good name), otherwise, select SAVE.
- If you get into the good habit of backing up your library often, you can keep the same name for the backup library and overwrite it as you add more citations.
