HarperCollins has an online manuscript site, authonomy.com where writers submit their unsolicited manuscripts to be read by book readers. These book readers endorse new talent and validate its commercial appeal as part of HarperCollins’ acquisitions process. The manuscripts which are voted to the top are guaranteed to be read by a HarperCollins editor each month.
Harper Collins just purchased three books straight from this manuscript site which were Miranda Dickinson's romantic book Coffee at Kowalski's, Steven Dunne's detective story The Reaper, and Lynne Barrett-Lee's real life story, Never Say Die. All three authors sold world rights as well.
