Not too long ago one of my works was accepted into Booktrope. Needless to say, I'm really pleased.
Bootktrope works differently from conventional publishers in precisely the same way that Uber differs from cab companies. Instead of a central controlling authority who schedules everything, Booktrope uses a cooperative control model. Authors, book managers, editors, proofreaders, cover designers, and all the various parts of taking a book from a draft to a publication that someone would actually purchase. Instead of the publisher, or in the case of an indie the author, putting up the funds and contracting what are in essence employees to do the work, the booktrope model has them work as a team for a percentage of the return. It spreads the risks and the returns.
Like Uber, Booktrope makes its money by coordinating the parts.
In some ways I think the method is a better fit for publishing than driving.
