Free professional computer organization magazines/journals, just pay shipping. (Or absolutely free if picked up in York Pennsylvania, US)
Communications of the ACM: 1998 half year. Years 1999-2012 are complete. 2013-2017 are missing some issues here and there, most are at least 6 issues per year.
Also have ACM Queue magazine 2 or 3 partial years.
Can take all or some. They are currently bundled by year. I don't know the interest for things like this but I would really like to avoid the landfill if possible. Let me know what you want and where you are and I'll check on shipping costs.
