Last year, authors, illustrators, developers, and entrepreneurs once again turned to Kickstarter, the crowdsourcing Web site, to finance a range of projects—from new e-book platforms to independent presses. More than 6,000 publishing campaigns were launched on Kickstarter in 2013, including over 1,600 works of fiction and nearly 1,000 children’s book projects. In all, contributors pledged $21 million to publishing endeavors (up from $15 million in 2012), with an average pledge of $3,540 per project.

“[In 2013], we saw innovative tools for writers, like a new open-source publishing platform for e-books, and we saw great resources for readers, like new tiny free libraries in small communities,” said Kickstarter spokesperson Julie Wood, referring, in the latter instance, to the expansion of Todd Bol’s Little Free Library Project. Over the course of the year, Kickstarter campaigns raised funds to build small “take a book, return a book” neighborhood libraries in Bargersville, Ind.; Saskatoon, Canada; Forest Acres, S.C.; and Portland, Ore., among other locations. “We also saw that authors and writers are using Kickstarter for more than just funds—they are building communities of supporters and like-minded people,” added Wood.
