The CD Journal and the CDSG Newsletter rely on the submission of articles, reviews, site visit reports, notes, comments, letters, inquiries, etc. from CDSG members and other interested parties.

The CDSG Press provides copies of back issues of the CDSG publications, past conference notes (which often contain a number of reproductions of important source documents and maps of the harbor defense area visited), and reproductions of important books and manuals.

The organization also hosts an annual conference at different harbor locations with field trips visiting the remaining harbor defense structures in the area, along with a series of evening presentations on coast artillery subjects.

The CDSG organization are also are advocates and provide funding through the CDSG Fund program for the preservation and interpretation of seacoast defense structures and history. The CDSG also is building a representative program to keep in regular contact with the various sites that were once coast artillery locations. This program is designed to exchange information and resources between the CDSG and the site locations.
