Reference citations in text are done using parenthetical referencing. Most usually, this involves enclosing the author’s surname and the date of publication within parentheses, separated by a comma, generally placed immediately after the reference or at the end of the sentence in which the reference is made, e.g. “Several reasons can be given for the lack of interest in the radio as a medium (Caldwell & Richardson, 1995).” However, it is also common for the authors to be the subject or object of a sentence. In such a case only the year is in parentheses, e.g. “Caldwell and Richard (1995) argue that there are several…” In all cases of citation, author name(s) are always followed immediately by the year, and years are never presented without author name(s) immediately preceding it. In the case of a quotation, the page number is also included in the citation. Up to three authors appear in full on first citation, e.g., Kling, Hyde & Buswell (1999) but subsequently as King et al.(1999). For four or more authors, indicate the first author followed by et al.
The APA style guide prescribes that the Reference section, bibliographies and other lists of names should be accumulated by surname first, and mandates inclusion of surname prefixes. For example, “Martin de Rijke” should be sorted as “Rijke, de M.” and “Saif Al-Falasi” should be sorted as “Al-Falasi, S.” For names in non-English languages, follow the capitalization standards of that language.
