I'm only halfway through this recently published volume by Polly McKenna-Cross and Janet Kamien, but I have already found it to be an invaluable resource in navigating process and possibility in the world of exhibit design.
The book approaches exhibit design as a collaborative effort between different advocacy stakeholders: institution, visitor, subject, design, and project. Combining original narrative with contributions from professionals working across the field, the reader gains an intimate look at the considerations each stake holder must make in order to produce a successful exhibit.
