 Chains of World Using Social Media is a book of dreams and hopes and inspiration and stories. It very much leads you through some of the social media platforms that are available to you if you want to try to make positive change in your communities. It deals with some of the larger groups out there like Black Lives Matter and Climate Change and some of the other organizations that have done great things. But most importantly, it takes you to some of the personal stories that I managed to collect for the book, including the librarian in Toronto who, using social media, created an onsite walk that brought community members together. It brought together stories of how here in San Francisco, people doing the Hidden Garden Steps project were able to use social media as part of their project. And it talks about things like shaping EDU, which is a global effort based out of Arizona State University. It shows how educators are using social media to try to change the face of learning in the digital era. Hope you enjoy the book. It's obviously available through the San Francisco Public Library, through independent bookstores and through the publisher, Roman and Littlefield.
