Here at Shareable, we're huge advocates for "Sharing Cities." Since our founding, we've connected thousands of people interested in sharing and published hundreds of stories about how cities can help them share more. But readers have frequently asked us, “What does Sharing Cities mean? Why are they important today?”

That's why we've been working with 20 researchers, community organizers, and policy experts from 10 countries to crowdsource a book about Sharing Cities. We’ll be releasing our new book, "Sharing Cities: Activating the Urban Commons," early next year.
