    I gave the scan that Colin MacLarty just shared on the mailing list a home on the nLab:

    Presently the pdf-link points to my Dropbox folder, as I keep forgetting the system password necessary to upload a file of this size to the nLab server. Maybe Mike or Adeel have the energy to upload it.

    I wonder if anyone finds anything surprising in the content of the notes, or has it all been absorbed?

    The note-taker throws in comments like “What in thunder do you mean by that Maclane?” (p. 142)

    I wonder if this is the only extant set of notes? (I don’t know much about the author.)

    “What in thunder” sounds like a Mac Lane-ism to me.

    he was probably a student in 1969.

    He may be the Ellis D. Cooper with genealogy

    Ph.D. Dalhousie University 1973 Canada

    Dissertation: Groupoids and Preorders

    Advisor: Barry Miller Mitchell

    He may be the Ellis D. Cooper with genealogy …

    That Ellis D Cooper has a facebook page where he lists a long employment history involving college teaching, hardware, software, and electronic music engineering, and highschool teaching. He has recently written a book, Mathematical Mechanics: From Particle to Muscle, involving among other things category theory and modeling skeletal muscle contractions that is suitable for high school AP students.

    The Dropbox link no longer works. Does anyone still have a copy of the notes?

    Check out the entry: Lectures on category theory, it points to a local copy of the document on the nLab server

    Thanks, I had somehow missed that the nLab page itself had been updated!

    At some point in the past, the technical team had increased the maximum file size that could be uploaded through the usual dialogue. It was probably after this that I uploaded the file (in revision 4, April 2017). Or was it? I forget.
