Kyosei Shakai Kenkyu Senta at Saitama University (埼玉大学共生社会研究センター)
This center holds primary materials on NGLs, NPOs, labor problems, consumer movements, citizens and residents' movements and environmental movements. In addition to taking over the privately run Jumin Toshokan's materials, the center has acquired collections from other sources. The amterials include complete runs of many "minikomi" organizational publications, plus trial records various kinds of social movement-backed lawsuits and original materials from some large scale reserach projects on labor issues. The Center is committed to open access.
