The Writings of Henry D. Thoreau is a project that aims to provide, for the first time, accurate texts of the complete works of American author Henry David Thoreau, including his journal, personal letters, and writings for publication.
Since the project was founded in 1966, Princeton University Press has published 18 of its volumes.
It is based at the University of California, Santa Barbara Library, and has been directed by Elizabeth Witherell since 1980.
The project has in the past been funded by the National Endowment for the Humanities (NEH) and the National Trust for the Humanities, and is now funded by UC Santa Barbara.
Images of the sixteen manuscript volumes Thoreau kept from 1854 through 1861 are available online by the courtesy of the Morgan Library & Museum.
