Every database has its Export feature in a slightly different location or a different process
You want to look for an "RIS Export" or "Export to EndNote" option.
Please note that some databases may give you two EndNote export options. You'll generally want to use "Export to EndNote" or "Export to EndNote Desktop" if you have EndNote installed on your computer. If you see "Export to EndNote Online" or "Export to EndNote Web", this will send your results to that version of EndNote in your web browser. The web version of EndNote is not as robust as the desktop version.
