The DSA Newscast

Since March of 11E9 (2013.), the DSA has been publishing The DSA Newscast, a (mostly) monthly newsletter, for the benefit of its members. Typically consisting of a headline article, news, Society business, and a poetical diversion, this continues to be published today. Initially, the Newscast is available only for members; after a new issue has been published to members, the prior issue is posted here.
