tations to information sources used or relied upon occur in two(2) places within a document. Firstly, "in-text" and secondly, with citations in full, as a Reference List at the end of the complete document.
The "in-text" citation, in brief form, occurs at the exact point in the text of the document where a quotation, a paraphrased idea, background concepts, etc, are introduced, discussed or mentioned. The second place is in the Reference List where the source is cited in full.
APA style requires that the surname of the author and the year of publication be inserted in the text at the appropriate point. The brief in text details of the author's surname and year of publication are enclosed in parentheses ( ).
