    Internet/Electronic Texts

    When documenting internet/electronic resources, the new edition of the APA Style Manual prefers the use of the DOI (Digital Object Identifier). The DOI is: a persistent unique code used to identify and retrieve a specific publication on the Internet, usually a journal article, web document, or other item of intellectual property.

    Eventually all electronic resources will have a DOI number. To see if an article has a DOI number, go to the following website and enter as much information in as possible about the article:

    Article found in one of the library’s Databases

    If the article contains the DOI number, then this should be used. If no DOI number if present, then you can either use the name of the database and the accession number or the URL of the homepage of the journal.

    The DOI number may or may not be listed in the library database. The DOI number, if an article has one, should always be found on the article itself.

    Article with DOI number:

    Hinduja, S. (2008). Deindividuation and Internet Software Piracy. CyberPsychology & Behavior11(4),

    In-text Parenthetical Citations

    Parenthetical references direct the reader to a specific page in a book, journal, or other source. They increase the validity of your work, by informing the reader of sources you have drawn upon whether you are paraphrasing or including a direct quote. The APA format keys parenthetical citations to the references which appear at the end of your paper.

    Parenthetical Reference Rules

    1. When making an in-text reference, a comma must be placed between the author’s name and the date of the publication.

    One marketing study (Smith, 2002) shows the need to focus on users, clients and customers.

    2. Do not include the author’s name and date if they are listed in text from which you are quoting.

    In Smith’s 2002 marketing study…

    3. References at the end of a sentence go inside the last punctuation mark.

    The marketing model in the digital age focuses on the type of customer (Smith, 2002).

    4. With a direct quotation include the page number, the author’s last name and the date of publication.

    Many businessmen have found that “the real value of marketing is to ensure the survival and growth of the company” (Smith, 2002, p. 52).

    5. The first time you make a parenthetical reference from a work with two to five authors, all of the author’s last names must be used. If you make a reference to the work in another part of your paper, you may put the last name of the first author followed by et al.

    Portfolio management (Smith, Jones & Black, 2002) is recommended as an effective tool in the management of people.

    There are many models of portfolio management (Smith et al., 2002).

    6. For electronic sources which do not have a page number, list the paragraph number.

    Field trials for cocker spaniels began in the United States in 1924 (American Kennel Club, 1992, para. 5).

    7. If you have two different authors with the same last name, you must include the first initial of the author’s first name within the parentheses.

    Marketing strategies are used by people from all walks of life from the President to the grocery stores to sports stars (A. Green, 2003).

    8. Personal letters, telephone calls, and other materials which the reader can not retrieve are not listed in the Reference page, they are cited within the text of the paper.

    Joe Smith (personal communication, January 10, 2003) confirmed the importance of marketing strategies.

    9. If you cite a corporate author, the author’s complete name must be listed in the reference. If a simple abbreviation is possible, include this in brackets. If you cite the same corporate author again, you may use the abbreviation in later parenthetical references.

    “In the 1890s most doctors learned through apprenticeships, and many did not attend medical school” (American Medical Association [AMA], 1993).

    All authors cited in the text of your paper must appear in your reference list.

    If you have any further questions, please consult a Reference Librarian.
