This is the cover from a 200 page 8.5 x 11 inch textbook published internally. IDK what the distribution of these was nor how many different volumes like this were published.

Other books published were as thick or thicker with much information packed into them. With regard to some of the work published internally in these books it was rather recursive to me as they referr me to my own work much of which was not published other than in these internal texts.

Many publications from ICIS, SPSE and other photo organizations exist that were only distributed to members or registrants of meetings and some articles were never published outside of these booklets. I have several of those as well.

I really don't know what to do with them except donate them to GEH at some point in time.
