ICMYI I wrote about the importance of being a citizen archivist. We've seen so much incredible art and writing from marginalized people, and we need to preserve it in the face of a huge, well-funded backlash.
This is something concrete you personally can do!

For folks who make zines, there's a zine special collection at San Diego State which includes all manner of self-published work. There aren't many better ways to preserve something than having it added to a university's special collection.
There are multiple USA zine & fanzine collections, some are general purpose, others have specific focuses like counterculture, LGBTQ, women, fanfiction. You can find them in many universities (Ohio, Texas, Michigan, Pennsylvania, California, Iowa) & some nonprofits owned. Google fan/zine archives
