It is very important to insure that any item listed in a parenthetical or in-text citation corresponds to an item in your reference list. Make certain that author, title, and publication information are listed exactly the same in both citation types.
APA uses parenthetical or in text citations where the last name of the author, date of publication, and specific page or chapter are placed in parentheses within the text. Examples may be found in APA section 8.
Most parenthetical citations, placed immediately after a quotation or paraphrase, must include the following elements as shown in section 8.10-11.
Narrative citations incorporate the author and publication date within the sentence. In most instances, the author's name will be given and the publication date placed in parentheses immediately after. In some instances, the date may be included in the sentence without parentheses.
When utilizing multiple sources in a single instance, group all of the sources together in a single note. Sources should be listed alphabetically in the order found in the reference list and separated by semicolons.
List two or more works by the same author in chronological order
To highlight specific works that are particularly relevant to your point, place those works first in alphabetical order. Then use a semi-colon and the phrase see also before listing additional citations also in alphabetical order.
If citing multiple sources in a sentence as a narrative citation, no specific order is required.
If no author is listed, refer to the work by title within the text and parenthetical citation.
If the author is officially listed as "anonymous," APA indicates that word should be treated as the author's real name in both the parenthetical citation and reference list.
References by the same author with the same publication date should be listed in chronological order by the specific date and then place a lower case letter immediately after the year in the in-text citation.
When citing more than one work by authors with the same last name, include the author's initials in all text and parenthetical citations in order to differentiate between works.
If a group name has a familiar abbreviation, include the abbreviation in brackets after the full name for the first usage and then utilize the abbreviation for the following citations.
If two groups share the same abbreviation and both groups are cited in a paper, spell out both group names every time.
