Hi .. try me .. i'm fast and accurate .. this searching task is my game. try me give me at least 3 and i'll get one of them if not all .. I usually search general in google, if it is not there i try linked in, twitter, Facebook. If he is a writer i'll start with blogs i'm sure they will have a hand on it. most importantly are the publishing companies.
Put in mind that writer are either old school, they use only a paper and a pen, or into social media, where you will find them everywhere to add their finger prints. this is why i mentioned you have a big chance that you will find one out of three. i said that based on a personal experience, i worked in a company before my boss asked me to get the addresses and emails of the most famous 500 female leaders in the world. i had their names, their job titles, their companies, but we finding all their emails was hard. i was able to find their addresses though?
Try me ..
