Works that establish or reconstruct the base of a discipline. Books in this series examine how a field organizes itself — its primary categories, its inherited assumptions, its load-bearing decisions — rather than working within the existing framework.
Works that introduce a new way of organizing existing knowledge. A frameworks title gives a discipline a new method of asking its questions, and a new way of recognizing when an answer has been reached.
Works that give the reader a tool — a method, a vocabulary, a discipline of attention. Reference titles, carefully built and slowly revised, intended to remain useful for a generation rather than a season.
Essential structural works brought into English for the first time, or retranslated with the rigor they deserve. Works whose absence from English is itself a structural problem.
