Salon.com's Laura Miller has an interesting article here on the future of authorial income, in which she spotlights Kickstarter as an excellent way for an author to raise funds for a novel project. Over the last couple of years the crowd-funding website has become a popular platform for indie authors and other publishing entities to employ when seeking the always-elusive financial support they need for books they can't/won't sell to publishers and other special projects.
What Ms. Miller doesn't mention in her piece is that Publishing has the second-lowest successfully funded rate of all the categories on Kickstarter; according to Writer's Digest only 32% of the book projects placed on the site are fully funded. I'll also take an educated guess that the majority of Kickstarter book-funding successes are enjoyed by established names who can attract a large number of donors and/or widespread interest from funder crowd. Still, Kickstarter has successfully funded 4,000+ publishing projects since it began in 2009, so if you already have a following and don't mind seeking financial aid in this manner it could help with the cost of producing an indie title.
