Does anyone know how to obtain a copy of this book? It's Aarhus Lecture Notes 30, 1971.

Maybe ask someone at Aarhus, e.g. @daniel gratzer?

I will send Anders Kock an email asking if we can make this publicly available on the nLab.

If the answer is yes, maybe we can ask the TAC editorial board to make it a TAC Reprint.

(Has anyone thought of doing that with any of the new posthumous Lawvere papers?)

Anders was very happy to have a scanned copy himself and has uploaded it to his homepage [0]. I have also uploaded it to the nLab as [1], findable via [2].

I have also contacted a maintainer of the Aarhus Math. Lecture Notes Series archive to see whether a copy can be included there.
