I was just having a look at Wikisources' logos on Wikidata, and there are quite a few that don't have one yet: https://w.wiki/x6V
I've tried to add as many as I can find, but if anyone happens to know the correct SVGs for the missing ones, it'd be great to complete the list. (Note that it's the 'logo image' not the 'image' property.)
Thanks, Sam.
