Illustration or diagram in a book [from Print source using APA 6th ed.]
APA does not expect these to be referenced separately from the work in which they appear. Please consult the appropriate page. Include the full work in your reference list. For your in-text citation, identify the full work, and give the page on which the illustration, etc., occurs. If you have transcribed a diagram or table, and included it as an appendix, your in-text citation can be to the appendix.
