We at WikiTree believe that the world’s information should be easily accessed by all, so we've created this extension, Sourcer, to make the life of our users easier. It's a simple way to get around the issue of trying to remember which websites to use when adding sources to a profile. If you’re starting a profile, you can simply select the Sourcer option, and then go to any record on the website. Then, you can click on the Sourcer icon on the left-hand side, and Sourcer will show you all the websites you can use. It even highlights which ones are free and which ones aren't.
