APA: Reference list

The American Psychological Association has established rules and conventions for documenting sources that writers can follow when they are putting together their reference list. The APA-style is one of the most common styles taught at and used by colleges, universities and other organizations, including several institutes of the HAN University of Applied Sciences.

The following overview describes the most important APA guidelines:

Please note
that a reference list is always written in alphabetical order, irrespective of the kind of source or material. 

Book

Author, A. (year of publication). Title of book. Location: Publisher.

  • A second or later edition is added between brackets after the title.
  • If there is no author but there is an editor, the editor is added between brackets in the same language in which the book is written.
  • If there are multiple authors or editors, an ampersand (&) is added before the final name.

Song lyric

When you retrieved the lyrics from an online source or from a book (this includes sheet music), the referral is analogous to the citing of an Internet source or a Book. You may need to add extra information in brackets to identify which score you used.

When referring to a musical recording on CD, cassette or other sound recording medium, your text citation consists of the name of the songwriter(s), date and track number. Your reference list should contain the original source. If the song is written by someone other than the recording artist(s), you may need to include the artists name(s). You may also need to include a second date when you are referring to a later recording.

Picture

The referral of a picture (like a photograph, chart, schedule) in your thesis or assignment, is analogous to the citing of a quote. The original source is mentioned in the reference list. In the text the picture is referred to as a quote, with its own serial number.

Pictures retrieved from the internet have their own URL. This URL can be found when clicking on the right button of your mouse on the picture, then select the option ‘Properties’. If this is not possible and no URL is available, you could use the URL of the website. The addition of [On-line picture] between square brackets is not obligatory, but does make it more clear to the reader that you are referring to a picture.

Interview

A published interview is referred to according to the reference format appropriate for the source (see Internet source, Book etc.).

When you have conducted an interview or survey by personal communication, e-mail, chat, phone, etc., you do not have to include the interview in your reference list because there are no recoverable data available for the reader. In addition to the reference list you may want to add a list of names and data from the interviews you conducted. When referring to a conversation or interview in the main text, you will need to add the term “personal communication” and the date on which the interview took place. Especially when you are quoting an interviewee (see third example), it is advisable to ask the person you are quoting for permission in advance. With second or later referrals you will need to write the name, personal communication and date again. 

 
Examples

  • …according to John Smith (personal communication, November 30, 2014) this is not the case…
     
  • …but this is not the case (J. Smith, personal communication, November 30, 2014) and will…
     
  • …John Smith (personal communication, November 30, 2014) e-mailed us that “this is not the case” and…

             
                    

Appendix

An appendix is a section at the end of a paper that includes information that is too detailed for the text of the paper itself. Each appendix has to be referred to in the main text.

The appendices section comes after your reference list. When the content of an appendix contains information retrieved from an outside source, cite the source within the text of the appendix and include the reference in your reference list.

If you want to include more than one appendix you will need to label them with the following letters: Appendix A, Appendix B, Appendix C, etc.

Owner of the data set. (Year). Title of the data set [Data set]. Location: Publisher.

  • A data set is a collection of research data (“raw data”). These data span a wide variety of topics and can be used to create a table or chart, for example.

Table

A table gives a well-organised overview of information and is particularly suited for statistics. A table consists of three or four parts:

1. Number and description: number of the table, making it possible to refer to the table in the text, and a description.
2. Column and row headings
3. Cells with data
4. Explanation (additional)

  • A table only has horizontal lines, above and below the column headings and below the last row.
  • Use only decimal points (no commas), make sure the points are spaced the same distance in every column.
  • With means, standard deviations or test statistics, a single number after the decimal point is enough. Only with probability values and correlation coefficients this is not the case.
  • When using a table from a book, journal, internet etc., this is considered a quote. The table will get a number in order to be able to refer to it (See: In-text quotations).
