Endnote creates a reference library. You can import references from scientific databases or add them manually. The program can handle large amounts of references, which you can back up and share via Endnote Online.
Endnote is integrated with Microsoft Word. The program continuously builds a bibliography, and supports many reference styles, e.g. Vancouver, APA and Harvard.
Clarivate Analytics, the manufacturer of Endnote, has tutorials and support at Endnote.com
