Referred to in Japan's Internet community as "jisui," (literally "cooking one's own meals"), the process involves feeding pages of a book through a scanner one by one to turn a work into digital form. Boosting the popularity of personal digitization is the emergence of portable devices such as Apple's iPad.If this is the trend in Japan with 20% of surveyed iPad using doing it, I expect it will become a trend elsewhere.
And what about copyright? The article notes that this is violation of copyright in Japan, but that the law is out of step with practice.
Thanks to Michael Porter (LibraryMan) for pointing me toward this article.
