The bibliographic style selected on the Configure Bibliography dialog determines how EndNote formats the citations in your paper and the references in the bibliography. The style is for text styles, punctuation, and sorting required for the citations and bibliography as well as which fields are included in the bibliography.
You can use the Format Bibliography tab to select a different style and reformat your document at any point.
For a typical installation, EndNote initially installs only the most popular output styles, although more the styles are available. See Installing Additional Output Styles
