We’ve all heard stories of comic book burnings from the ’40s and ’50s. We know these stories were more than merely apocryphal—but how many burnings actually took place?

Nicholas Yanes is trying to answer that question.

As part of his dissertation on the history of Mad Magazine and EC Comics, he’s been reviewing primary sources in search of accounts of those public protests, and has been able to find 16 documented cases.

But there were more, weren’t there? Or … do we just think there were more?

He’s put out a call in hopes that the Internet group mind can locate any others that exist. So if you have any info, reach out to him on Twitter or Facebook.
