Some time last night LibraryThing Common Knowledge hit three million edits.
Common Knowledge, introduced back in 2007, is LibraryThing’s “social cataloging” experiment—a fielded wiki for all the data that you can’t find elsewhere.
I recently introduced two features that make Common Knowledge better. Inter-language visibility allows members to see what members using non-English version of LibraryThing have entered into Common Knowledge, and even to edit one language’s Common Knowledge within another site. “Borrowing” data between languages shows Common Knowledge across languages, with a notice, and allows you to edit the entry to bring it into your language’s Common Knowledge. Together, they solve a long-standing social problem with Common Knowledge–how to make sure information flowed easily, but appropriately across LibraryThing’s many sites.
