APA Citation Style : Unpublished or informally published works

APA Citation Format (Commonly used for psychology and other social science papers)

Format for unpublished and informally published works

Author, A. A. (Year). Title of manuscript. Unpublished manuscript [or "manuscrip submitted for publication," or "Manuscript in preparation"].

Citing a Course Pack or Custom Textbook

Jeff Hume-Pratuch, an editor at APA, provides following guidance and examples:

Previously Published Articles or Chapters
The source should be clearly identified as part of the copyright/permissions statement, which is required by law.  In this case, you can eliminate the middleman—just cite it as if you found it in the original source:

Wenner, A. M. (1962). Sound production during the waggle dance of the honey bee. Animal Behaviour, 10, 79–95. doi:10.1016/ 0003-3472(62)90135-5.

Original or Unattributed Material (unpublished material in course packs)
Since the only source for this material is the course pack itself, treat it as part of an anthology compiled by the instructor and published by the university. If authorship is not stated, treat it as an unauthored work. The title of the compilation is whatever is on the cover or title page—often (but not always) this consists of the course name and number, as in the first example below:

Diagram of the tibia–basitarsis joint in Apis melifera. (2011). In B. Haave (Comp.), NEU 451: Movement and perception (pp. 44–45). Davenport, IA: St. Ambrose University.

MacGyver, A. (1990). Five steps to repelling an attack by killer bees. In R. D. Anderson (Comp.), Selected readings in survival, escape, and evasion (pp. 31-34). Davenport, IA: St. Ambrose University.

Supplemental Material (such as CDs, DVDs, or online materials that are accessible only with the purchase of the text)
 Cite them as supplemental materials:

“Varroa mite blues” and other songs of the honey bee [Supplemental material]. (2012). In B. Haave (Comp.), NEU 451: Movement and perception (pp. 44–45). Davenport, IA: St. Ambrose University.

Materials that are only available on instructor's course management site

Jeff Hume-Pratuch, an editor at APA, provides guidance in his blog post How To Cite Course Packs, Custom Textbooks, and Other Classroom Copmendiums:

Technically, material that is available only from the instructor via course management software such as Blackboard should be cited as a personal communication (see section 6.20 of the Publication Manual and the APA Style Guide to Electronic References, p. 31). This is because, in APA Style, references must lead to recoverable data. (Hume-Pratuch, 2012).

So there would be no reference item, but an in-text citation similar to the following would be needed: 

T. Jackson (personal communication [Lecture notes], November 30, 2015) stated that ...

Citing instructor’s powerpoint file or other materials

Timothy McAdoo, Documentation and Training Specialist, APA PsycINFO, in his blog post How to Cite a Class in APA Style provides guidance below:

If the instructor has posted the materials somewhere online, you can cite them directly. But, it’s more likely that he or she is the only source for the materials. In that case, cite as a personal communication (see the Provide a Reliable Path to the Source section on what belongs in a reference list). (MaAdoo, 2012).

Notes taken in class / class handouts

Timothy McAdoo, Documentation and Training Specialist, APA PsycINFO, in his blog post How to Cite a Class in APA Style provides guidance below:

Because these notes will not be a retrievable source for most readers, cite them as a personal communication (see the Provide a Reliable Path to the Source section on what belongs in a reference list). (McAdoo, 2012).

Since in APA Style, personal communications are listed only in text, not in the reference list (APA Publication Manual, 6th ed., section 6.20). Provide initials as well as the surname of the person involved, and give as precise a date as possible. You would have an in-text citation for a personal communication similar to the following:

According to T. Jackson (personal communication [Lecture notes], September 2, 2015) ...
