EndNote groups citations into "libraries" with the file extension *.enl and a corresponding *.data folder.

There are several ways to add a reference to a library: manually, exporting, importing, connecting from EndNote. The program presents the user with a window containing a drop-down menu to select the type of reference they require (book, newspaper article, film, congressional legislation, etc.), and fields ranging from the general (author, title, year) to those specific to the kind of reference (ISBN number, abstract, reporter's name, running time, etc.) Most bibliographic databases allow users to export references to their EndNote libraries.
