EndNote automatically checks for program updates when you open the application.
You can manually update EndNote with free incremental program enhancements.
To update your copy of EndNote:
From the EndNote menu, select Check for Updates to download the latest updates to the EndNote program.
From the Help menu, select Web Styles Finder to direct your browser to an EndNote online page where you can download from the full collection of output styles.
We continually update output styles, filters, connection files, and Microsoft Word templates. The latest versions are included with program updates, but you can also download the latest files at any time from our EndNote Web site.
