Determining what intellectual property is in the public domain is fairly simple: when a patent or trademark has expired, the protected material comes into the public domain. A number of people and institutions are making literature, reference materials, and historical works that are in the public domain available on the Internet. Two examples are The New Bartleby: A National Digital Library at www.bartleby.com, and the Project Bartleby Archive at www.columbia.edu/acis/bartleby where you can find selected works of Theodore Roosevelt, The Oxford Book of English Verse, Bartlett's Familiar Quotations, W. E. B. Du Bois' The Souls of Black Folk, and many more significant works. The philosophy of Project Gutenberg at www.promo.net/pg is "once a book or any other item (including pictures, sounds, and even 3-D items can be stored in a computer), then any number of copies can and will be available." In spite of the availability of vast amounts of literature and information in the public domain, some people propose that all information wants or needs should be free. The article "Against Intellectual Property" at www.eff.org/
pub/Intellectual_property/against_ip.article represents one side of this debate. "Royalties, Fair Use & Copyright in the Electronic Age" at www.educause.edu/
pub/er/review/reviewArticles/30630.html presents another side of this debate.
