HarperCollins, the book publishing company owned by News Corp (NYSE: NWS). is launching its books social networking site called Authonomy (finally, a great name for a relevant social network), with the intent of using it to discover new and unpublished authors, and hoping the community will vet these manuscripts and ideas. The site is launching in UK for now, after three months of private testing...it was announced late last year. While HarperCollins is not promising book deals, it has committed to read the 10 top-rated submissions to Authonomy every month and hopes other publishers will also join the site, reports FT.com. Authors of any genre can upload the first 10,000 words or more of their bestsellers-in-waiting, though it remains to be seen whether it can build in checks and balances to prevent any unauthorized or pirated use, or even any allegation of people lifting off ideas.
