The following appendices list d’Holbach’s publications and the newspaper and journal articles that they provoked. The product of several years’ original archival research, they show the footprint of a largely unknown public sphere firestorm that broke out in the 1770s and 1780s. They include almost 100 contemporary books and pamphlets and more than 200 periodical articles, many of which have never been previously linked to the baron. They reveal an extraordinarily varied body of reaction, including philosophical responses by the likes of Frederick ii and Voltaire, official proclamations, anti-philosophe novels, poems, theological treatises and epistolary fiction. They should leave little doubt that, despite having attracted the attention of relatively few historians, d’Holbach’s works mattered to his contemporaries.
