I was fascinated to read of the continued progress of some of Symbian's 'Wiki books' over on the Symbian Blog today. Essentially, these slightly niche guides and reference texts are being created in collaborative style by a number of authors, all contributing online into a 'wiki', a hypertext shared document. The 'wiki books' can then be electronically massaged into free electronic 'ebooks' or even passed over as needed to an on-demand book printing service. And it goes without saying that content can be kept up to date a lot more easily than with conventional '100% paper' titles.
