I am offering (for free) ACM publications I?ve accumulated over 40+ years as a subscriber: CACM (Communications of the ACM) 1967-2013 ACM Computing Surveys 1972-1997 SIGOPS Operating System Review 1972-2011 TOCS (ACM Transactions on Computer Systems) 1983-1991 In all, they fill about 7 file boxes. There are some gaps because I?ve already donated batches to ACM and the Computer History Museum to fill gaps in their archives. I live in Mountain View, California, and it would be best if you could pick them up. If you?re willing to pay for postage and packaging, I could mail them media mail rate within the US. Paul McJones
