Most of the styles included with EndNote produce standard bibliographies without including additional information such as notes or abstracts. Two of EndNote's standard styles are the Annotated style and the Show All Fields style. The Annotated style includes the Abstract field after each reference, and the Show All Fields style lists all of the field names and the information found in those fields for each reference.
See Modifying Style Templates for information about editing and creating styles. These are two examples of common ways you might want to edit styles for your printouts or for stand-alone bibliographies: Creating Annotated Bibliographies and Printing Only the Notes.
