Project Gutenberg keeps its administrative and financial structure to the bare minimum. Its motto fits into three words: "Less is more." The minimal rules give much space to volunteers and to new ideas. The goal is to ensure its independence from loans and other funding and from ephemeral cultural priorities, to avoid pressure from politicians and others. The aim is also to ensure respect for the volunteers, who can be confident their work will be used not just for decades but for centuries. Volunteers can network through mailing lists, weekly or monthly newsletters, discussion lists, forums and wikis. Donations are used to buy equipment and supplies, mostly computers, scanners and blank CDs and DVDs. Founded in 2000, the PGLAF (Project Gutenberg Literary Archive Foundation) has only three part-time employees. More generally, Michael Hart should be given more credit as the inventor of the electronic book (ebook). If we consider the ebook in its etymological sense--that is to say a book that has been digitized to be distributed as an electronic file--it was born with Project Gutenberg in July 1971. This is a much more comforting paternity than the various commercial launchings in proprietary formats that peppered the early 2000s. There is no reason for the term "ebook" to be the monopoly of Amazon, Barnes & Noble, Gemstar, and others. The non-commercial ebook is a full ebook, and not a "poor" version, just as non-commercial electronic publishing is a fully-fledged way of publishing, and is as valuable as commercial electronic publishing. Project Gutenberg etexts--the term used originally--have been renamed ebooks, to use the recent terminology in the field. In July 1971, sending a 5K file to 100 people would have crashed the network of the time. In November 2002, Project Gutenberg could post the 75 files of the "Human Genome Project", with files of dozens or hundreds of megabytes, shortly after its initial release in February 2001 as a work from public domain. In 2004, a computer hard disk costing US $140 could potentially hold the entire Library of Congress. And we probably are only a few years away from a USB drive--or an equivalent storage disk--capable of holding all the books on our planet. What about documents other than text? In September 2003, Project Gutenberg launched Project Gutenberg Audio eBooks, with human-read ebooks. Computer-generated ebooks are "converted" when requested from the existing electronic files in the main collections. Voice-activated requests will be possible in the future. Launched at the same time, the Sheet Music Subproject contains digitized music sheet, as well as a few music recordings. Some still pictures and moving pictures are also available. These collections should take off in the future. But digitizing books remains the priority, and there is a big demand, as confirmed by the tens of thousands of books that are downloaded every day.
