EndNote is a commercial reference management software package, used to manage bibliographies and references when writing essays and articles. It is produced by Thomson Reuters. 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, abstract, reporter's name, running time, etc.). Most bibliographic databases allow users to export references to their EndNote libraries.
