The DSA Newscast
From March of 11B9z (2013d) through November 1205z (2021d), the DSA published The DSA Newscast, a (mostly) monthly newsletter, for the benefit of its members. It typically consisted of a feature article, dozenal news, Society business, and a poetical diversion. 0 Each Newscast issue would initially be available only for members via e-mail; once a new issue was published to members, the prior issue would be posted here.
Note: These newsletters have been left unedited from their original content, and unfortunately they now contain many obsolete URLs. However, where possible, updated URLs are provided in the issue summary pages here, which you can link to by clicking on the issue titles below. In particular:
- This website was reorganized in January 120Az (2026d). No content was deleted, but articles, resources, and Bulletin issues are now at new URLS. Wherever a Newcast issue linked to such content, its issue summary page contains the updated URL.
- The DozensOnline forum was migrated from hosting on Invisionfree to hosting on Tapatalk. The old Invisionfree URLs no longer exist and unfortunately will now connect you to questionable content. Wherever a Newscast issue linked to an Invisionfree URL, its issue summary page now provides the equivalent Tapatalk URL.
- External links to other sites have occasionally gone extinct, but often could still be found archived at Wayback Machine.
