Question: What is the process for reporting unreported sales? What email address do I use? or is there an online form? In my situation I found out (through Google books) that a publisher put one of my images in a book. The book is due to be on the market in 4 months. I suppose the publisher submitted to Google books early. What is the appropriate time frame to report an unreported sale? Should I wait until the book is on the market?
