Today's Times has a lengthy article about the 'latest venture [which] will revolutionise the book-publishing industry, turning us all into potential J.K. Rowlings.' Its main thrust is an interview with the founder of Lulu.com. Then there are links to a number of case studies of writers who went the Lulu.com route, and some data on costs and likely sales of self-publishing ventures.
Nothing very new here, I suspect, for most readers of this blog.
