According to .Wikipedia:
"Bartleby.com is an electronic text archive, headquartered in New York and named after Herman Melville's Bartleby the Scrivener. It was founded under the name "Project Bartleby" in January 1993 by Steven H. van Leeuwen as a personal, non-profit collection of classic literature on the website of Columbia University. The original founder is now chairman and president of the privately held company. Its main source of revenue seems to be web advertising."
