The second key element of documentation is the list of sources used in writing the paper. This list is called Works Cited in the MLA style and References in the APA style. The format will differ depending on the style required by the instructor.
The Works Cited or References list is alphabetical by author and includes descriptive information about all the sources used in the essay or research paper.
Every type of source used must be documented in the proper format: books, journal articles, web sites, newspaper articles, television shows, films, email, etc. Each has a specific format for documentation.
