Dear colleagues, I am thrilled to announce the 20th Anniversary Special Issue of The Journal of Community Informatics is available online. https://openjournals.uwaterloo.ca/index.php/JoCI/issue/view/661 As Peter Johnson and I explain in our editorial, the first issue of The Journal of Community Informatics was published by Michael Gurstein on October 1, 2004. Since then the journal has continued to remain the open access, peer reviewed journal featuring contributions at the intersection of community informatics research, practice, and policy. We invite you to read the full special issue featuring nine essays from leaders in the field.
