Major Citation Elements

Attributive Phrases

Whether you are summarizingTo give a short version of the main points of a text., paraphrasingThe use of different words to express the meaning of an original text or speech., or quotingTo use the exact words of someone else in a writing. Quotes are indicted in a writing using quotation marks and attributive phrases. a source, it is important to provide contextThe larger setting in which something happens; the "big picture.", so you should include an attributive phraseA short introduction to source material that identifies the author and often the title of a work that will be quoted or discussed in an essay or research paper. to indicate to the reader that you are incorporating a source. An attributive phrase gives credit to the author of the original work. It is used in tandem with an in-text citationInformation about a source, such as the author, date, and page number, in an essay or research paper that helps readers find the source in the works cited or references page. There are different rules for how to use in-text citations depending on the context of the citation and the style of formatting you are using., which is the information in parentheses.

APA attributive phrases:

Thomas (2011) writes that Evans intended to "inspire a new generation of playwrights" (p. 42).

According to Thomas (2011), Evans wrote best at his home in Florida, "rising early and finishing late" (p. 53).

In-text Citations

When you incorporate a source in your essayA short piece of writing that focuses on at least one main idea. Some essays are also focused on the author's unique point of view, making them personal or autobiographical, while others are focused on a particular literary, scientific, or political subject. , you need to include in-text citations in addition to attributive phrases. Together, attributive phrases and in-text citations give readers the necessary information to be able to find the original source listed in the references pageAn alphabetized list of publication information about the sources used in an APA-formatted essay or research paper..

APA style in-text citation requires the author's last name, the year of publication, and a page number, preceded by "p." for "page" (if the source has page numbers and a specific page is referenced).

Example of an APA in-text citation without an attributive phrase:

One study indicates that artists who live in the South are "more prolific" (Miller, 2004, p. 7).

In APA style, if the author's name is mentioned in the attributive phrase, the year of publication should follow it and the page number should be included at the end of the sentence.

Example of an APA in-text citation with an attributive phrase:

Miller's (2004) study indicates that artists who live in the South are "more prolific" (p. 7).

Longer quotations are formatted and cited differently than shorter quotations. APA style requires that you use block quotationA copy of a long section of a text or speech, set off from the rest of a text. Block quotations, like direct quotations, are exact repeats of wording, but because of their length they are indented or printed in a different font rather than placed inside quotation marks. format (also called indented format) for quotations that are longer than forty words.

You should indent every line of a block quotationA copy of a long section of a text or speech, set off from the rest of a text. Block quotations, like direct quotations, are exact repeats of wording, but because of their length they are indented or printed in a different font rather than placed inside quotation marks. from the left margin by one-half inch and maintain double-spacing. Quotation marksA set of single or double inverted commas (' ' or " ") that are placed around a word or passage to mark the beginning and end of a direct quotation or a title. are not required since indentation makes it clear that the material is quoted. Introduce the quote with an attributive phrase, and place an in-text citation after the period at the end of the quotation.

Example of APA block quotation format:

Jarvis (2012) mentions George's extreme attention to detail:

  George would spend hours combing through his work for mistakes, long before
  submitting it to his editors. Pride apparently dictated that he present them with fully
  proofread copies. These hours of attention to minute discrepancies may have cost him
  his eyesight in the end. (p. 14)

References Page

In-text citations do not include all of the information to find the original source, so writers include a list of citations at the end of the paper with all of the information needed to locate a source. APA style refers to this list as a references page. The references page comes at the end of the work and includes all available information about a source, including article title, journal/book title, year published, the authors' first initials and last names, publisher, and place of publishing. These details vary by the type of source used and since there are about seventy different types of sources for APA, you should refer to an APA style guideA set of rules for punctuation, grammar, and other facets of writing, used to produce consistency and promote understanding. Different publications and types of writing often follow different style guides. Well-known style guides in the U.S. include The Chicago Manual of Style, the MLA Style Manual, and the Associated Press Stylebook. to confirm the correct citation model to use. All sources on a references page should be listed in alphabetical order.

Comparing MLA and APA Styles

MLA style and APA style are two common systems of citation, that is, sets of rules for how to cite sources and how to format and punctuate the various parts of a research paper. For most English and some humanities courses, you will be asked to use MLA style; for most social sciences and some other courses, you will be asked to use APA style. See the chart below for the major differences between MLA style and APA style.
