How would you cite a lab notebook in ACS format?
According to the ACS Style Guide, lab manuals/notebooks should be cited like books. If the lab manual was commercially published by a regular publisher, you would cite it like any other book. If the manual was written by your instructor/department, treat the manual as a book authored by the instructor and published by the university:
Example: Bird, P. Chemistry 206 Laboratory Manual; Concordia University: Montreal, QC, 2010; p 21.
If you want to cite your own lab notes, that would be treated as "unpublished material" "not intended for publication" (pp. 315-316 in the ACS Style Guide, 3rd. ed.). Here is the basic format:
Author. Affiliation, City, State. Phrase describing the material, Year
Example: Smith, B. R. University of the Sciences in Philadelphia, Philadelphia, PA. Laboratory notes for CH 203: Organic Chemistry Laboratory I, 2016.
For notes on lectures and other oral communications, treat this like an oral presentation given at a meeting or conference (pp. 307-308 in the ACS Style Guide).
Example: Robidoux, S. CHEM 324 Lecture on Stereochemistry. Presentated at Concordia University, Montreal, QC, September 16, 2009.
