If the concept and practice of collaborating interests you, I’d highly recommend this book, Group Work by Temporary Services. It’s available through Half Letter Press. It dives into the reality of collaborating, and discusses how working together in groups works and doesn’t work.
"This book provides unique insights into the workings of groups as it is conceived, planned, and orchestrated by a several people who have first-hand experience with the various misconceptions that the individual-centric art world holds towards groups and their practices." —Katy Asher
