Community Science Forum
We are renaming our publication to include a wider range of scientific activities. Grassroots Mapping Forum is now the Community Science Forum.
Read about cutting edge techniques in hacking environmental science in our "Community Science Forum", our community research journal/archive/zine/map, where we share ideas, techniques, and stories from the Public Lab community.
The Community Science Forum is printed on a 22.75x35" sheet of acid-free paper, and includes a full color reproduction of our projects along with essays, illustrated guides, and interviews. It's a great way to stay abreast of the latest in the DIY environmental science movement.
