La BNU selon Kevin Kelly – faits et chiffres
– From the days of Sumerian clay tablets till now, humans have « published » at least 32 million books, 750 million articles and essays, 25 million songs, 500 million images, 500,000 movies, 3 million videos, TV shows and short films and 100 billion public Web pages. All this material is currently contained in all the libraries and archives of the world. When fully digitized, the whole lot could be compressed (at current technological rates) onto 50 petabyte hard disks.
– Nearly 100 percent of all contemporary recorded music has already been digitized, much of it by fans. About one-tenth of the 500,000 or so movies listed on the Internet Movie Database are now digitized on DVD. But because of copyright issues and the physical fact of the need to turn pages, the digitization of books has proceeded at a relative crawl. At most, one book in 20 has moved from analog to digital.
– Stanford University is scanning its eight-million-book collection using a state-of-the art robot from the Swiss company 4DigitalBooks. This machine (…) automatically turns the pages of each book as it scans it, at the rate of 1,000 pages per hour.
– Superstar, an entrepreneurial company based in Beijing, has scanned every book from
900 200 [correction faite par KK] university libraries in China. It has already digitized 1.3 million unique titles in Chinese, which it estimates is about half of all the books published in the Chinese language since 1949. It costs $30 to scan a book at Stanford but only $10 in China.
– about 75 percent of all books in the world’s libraries are orphaned. Only about 15 percent of all books are in the public domain. A luckier 10 percent are still in print. The rest, the bulk of our universal library, is dark.
Ce dernier fait est peut-être le plus important et devrait être au centre de toutes les discussions sur les bibliothèques numériques (BNE et autres).
Il y a beaucoup d’autres choses à tirer de l’article de Kelly, en particulier toute l’élaboration sur le modèle économique fondé sur la copie vs. le numérique. Mais c’est une gageure de prétendre résumer cette synthèse!
