Indirect sources (also referred to as secondary sources)

Secondary source (When an author quotes another author) (Sec. 8.6 APA Publication Manual, p.258)

  • APA cautions that you should, whenever possible, take material from the original source. Sometimes, however, only a secondary/indirect source is available.
  • When the year of the indirect source is known, include it in the text.
  • Only the source you have in hand is the one that goes into your Reference list.

Format
