The annual Symposium on Principles of Programming Languages is a forum for the discussion of all aspects of programming languages and systems, with emphasis on how principles underpin practice. Both theoretical and experimental papers are welcome, on topics ranging from formal frameworks to experience reports.
ACM has offered SIGs the opportunity to run a three-year experiment to make conference proceedings open-access for a month around the conference. Also, SIGs can make the most recent year's proceedings open-access, until the next one comes along. See ACM web page about the experiment.
