This guide provides some examples on how to document sources in APA citation style. It is based on the 6th edition of the “Publication Manual of the American Psychological Association and also other references as listed under Acknowledgement.
To view how sources are cited in APA style, you may click on the tabs to know more.
Include the author, year of publication, and the page number for the reference (preceded by "p."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.
If the author is not named in a signal phrase, place the author's last name, the year of publication, and the page number in parentheses after the quotation.
Place direct quotations longer than 40 words in a free-standing block of typewritten lines, and omit quotation marks. Start the quotation on a new line, indented half inch from the left margin. Type the entire quotation on the new margin. The parenthetical citation should come after the closing punctuation mark.
If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (although it is not required.)
Use author’s surname and publication year.
Use ampersand “&” to join names; or if the reference is part of sentence, use “and”.
List all the authors in the signal phrase or in parentheses the first time you cite the source. In subsequent citations, only use the first author's last name followed by "et al." in the signal phrase or in parentheses.
Use the first author's name followed by et al. in the signal phrase or in parentheses.
(Add a, b, c … with the order of the listing based on the letter-by-letter alphabetical order of the title)
Mention the organization in the signal phrase or in the parenthetical citation the first time you cite the source.
If the organization has a well-known abbreviation, include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations.
Cite by the title which should be italicize, and date
When your parenthetical citation includes two or more works, order them the same way they appear in the reference list, separated by a semi-colon.
If you use a source that was cited in another source, name the original source in your signal phrase. List the secondary source in your reference list and include the secondary source in the parentheses.
For interviews, letters, e-mails, and other person-to-person communication, cite the communicator's name, the fact that it was personal communication, and the date of the communication. Do not include personal communication in the reference list.
