From Richard Weisgrau's article
Gentle Reminder"During my forty years in the photography business, I have learned that few clients have any system for tracking the rights they purchase. Most licenses they receive are usually part of an invoice that ends up in the accounts paid folder of the accounting department."Richard, you're absolutely correct and I have also run into this problem more than once over the years. Luckily, I have a good system for tracking all of my image usage licenses.
