This pioneering online catalogue raisonné was released in 1996. The comprehensive site includes van Gogh's paintings, drawings, letters, letter sketches, and graphic works, building a virtually complete inventory of over 4,300 documents pertaining to the artist's work. The catalogue raisonné can be searched chronologically or by subject. Other features include user forums, a discussion of fakes with links to other articles and resources, and a geographical guide to the paintings. A CD-ROM edition of the catalogue was published in 2002 under the title "Vincent van Gogh: The Complete Works" (Sharon, MA: Barewalls Publishing).
