The style selected from the Output Styles submenu of the Edit menu (or the style menu on the toolbar) determines how references are formatted for the preview in the Library window as well as for the Format Bibliography, Format, Print, Export, and Copy Formatted commands.
By default, EndNote’s standard bibliographic styles are installed in your Output Styles menu:
Annotated: generates an Author-Date style bibliography with abstracts.
APA 6th: Displays the first six authors (or editors) followed by the text preset to ( “, ...”) followed by the last author (or editor).
Author-Date: generates bibliography alphabetized by author name, and in-text citations with Author and Year.
MHRA (Author-Date): Based on the Modern Humanities Research Association style in which a footnote number is inserted in the text.
Numbered: generates a numbered bibliography with corresponding numbered in-text citations.
Show All Fields: generates a list of the references as entered, including all fields and the names of the fields.
Turabian Bibliography: Includes two options for citing sources: the notes-bibliography style and the author-date style.
Vancouver: Generates an Author-Number style bibliography.
Mark individual styles as your favorites in the Style Manager to have them appear in the Output Styles menu, the style menu in the Main toolbar, and the confirm formatting dialog.
