Teachers Pay Teachers is a freewheeling online market where entrepreneurial educators sell lesson plans, powerpoints, and other didactic materials to each other. The site is a massive resource, with a blend of both free and paid content. It is big business, too. By their own account, the company has paid out nearly $80 million to contributors.
I was surprised, on browsing TpT yesterday, to discover several especially ambitious contributors packaging public domain photographs for sale. That's odd. Public domain images are already open for anyone to use- are people really shelling out cash for what can be Googled for free? Apparently so.
There was nothing dishonest about the items. The photos' public provenance was clearly explained. Yet the practice feels...strange. In the same way it feels strange that some companies bottle tap water, when the same product is available from municipal faucets. Are fools and their money being parted?

Perhaps, but on reflection, I don't think so. Online image searches typically return a tangle of copyrighted works, Creative Commons-licensed copyrighted works, orphaned works, and public domain images. What's worse, most images aren't labelled as belonging to any of those categories, and those that are often erroneously bear the wrong one. As long as online image use remains an intellectual property minefield, a market for paid clarity is only natural.
