These are documents / journals from the Association For Computing Machinery - scholarly journals from the 1970s. 

I am selling 4 ACM Surveys from 1976 and 1977 and 11 ACM Communications journals - from 1977.  15 documents in all. 

They are all in good condition. 

I have had these since I was a computer science student in 1970s and would like to pass them along. They are fun to look at and would make great decorative pieces - if you are in to the vintage computing vibes!
