The Tout Voltaire database brings you in fully-searchable form all of Voltaire’s writings. Included are all of Voltaire’s works apart from his correspondence, which can be searched separately, as part of the Electronic Enlightenment project. Editions used to establish this database are clearly marked; when possible we have included Voltaire’s notes, and some variants depending on the edition.
The Voltaire Foundation is currently publishing the Complete works of Voltaire in print — the first definitive critical edition of his complete writings. An online version of this edition is planned sometime after 2018. In the meantime, this plain text version of Voltaire’s writings (without critical apparatus or notes) is the most reliable version available anywhere on the web.
This research tool is made available free of charge by the Voltaire Foundation (University of Oxford) and the ARTFL Project (University of Chicago).
