Borrowed from a colleague who admitted he hadn't read it.
Read while waiting for my phone to be transferred from one carrier to another (which means had a lot of time).
Found it rather not what I thought it might be, and also rather annoying in terms of getting to the text of the chapters. I thought there would be either more information about the designers methods, or that perhaps the book itself was giving case studies of people collaborating together, but no…
That said, and knowing some of the designers and writers involved, some it was mildly enlightening; I did encounter work and designers I hadn't known of and appreciate that.
