It is important for students to include an acknowledgement page in their research papers. Leaving out sources leaves the student open to accusations of plagiarism, as the absence implies that the paper is derived solely from their ideas. The format of the paper and the sources cited within and at the end of it are usually in one of the three major styles: MLA, APA and CMS. The style guide
. followed depends on the academic discipline that has assigned the topic.MLA format, the style guide espoused by the Modern Language Association, is the most commonly used method of formatting citations and is the default when no other method is preferred. Most papers written in English courses and most other humanities are in this format. Some key features of this style include in-text parenthetical citations that reference the author and page number, double-spaced text, single spaces after punctuation and a separate works cited page. Source URLs are not required as long as title and author information are cited.APA style is the standard format for journal articles, developed by the American Psychological Association. This format is most commonly seen in psychology courses as well as other social sciences like sociology. The four major components of a paper created in APA format are a title page, an abstract (summary), content, and an alphabetized reference page. In-text citations consist of author, page number and publishing date and must include a corresponding full source entry in the references list.CMS, The Chicago Manual of Style, is the preferred method of styling for papers related to history and is also preferred by many publishers. This method emphasizes the use of numbered notes to learn more about a fact and reference sources instead of in-text citations. Writers using this style can choose to use footnotes, endnotes, or a combination of the two. Footnotes place further information at the bottom of the relevant page, while endnotes list all of the additional information after the main body of the paper.More reference links: http://owl.english.purdue.edu/owl/resource/949/01/ http://writing.wisc.edu/Handbook/Documentation.html
