Emergency INDEX is an annual print publication documenting performances that occurred in one calendar year. Begun in 2011, INDEX was conceived as a "state of the field" publication that could present a year-to-year view of the issues, techniques, and challenges that performance makers dealt with in the work they actualized. Every year since then, INDEX has published hundreds of documents of performances made in various genres and media, for different audiences and purposes, and in a wide variety of venues, cities, and countries. Each annual volume includes three back-of-the-book indexes: an index of terms, an index of places, and an index of contributors. Taking as its starting point actual performances described by the artists who made them, INDEX proposes building your performance theory from the ground up. site
