“They Will Catch on Fire”: Michigan Library Asks Patrons Not to Microwave Their Books

Last month, the Plainfield Township branch of the Kent District Library (KDL) in Grand Rapids, Michigan, took to Facebook to share a cautionary tale about burning books.

It wasn’t a summary of Ray Bradbury’s Fahrenheit 451, nor did it have anything to do with a metaphorical protection of free speech. Instead, the post showed a scorched edition of Window on the Bay by Debbie Macomber, which had apparently been microwaved in an ill-conceived attempt to burn off any coronavirus germs.

As the post explained, each book is outfitted with a radio frequency identification (RFID) tag—a more efficient alternative to barcodes, which must be scanned individually and at close range. But since RIFDs contain metal, “they will catch on fire in the microwave.”

“I don't know if it was something that they saw on the news—that they thought maybe the heat would kill COVID-19,” the library’s regional manager Elizabeth Guarino-Kozlowicz told the Detroit Free Press.

Exposure to high heat could indeed kill the virus. According to the World Health Organization, temperatures of 132.8°F or above can eliminate the SARS coronavirus, which behaves similarly to this newer strain (SARS-CoV-2). That said, we still don’t know exactly how heat affects SARS-CoV-2, and nuking a novel is a horrible idea no matter what.

Food & Wine reports that KDL workers are quarantining all returned library books for 72 hours to make sure all coronavirus germs have died before checking them back into the collection. As for the fate of the charred volume, KDL told Mental Floss that the borrower has been billed for it. After they pay the fine, they’ll get to take it home for good.

If you’re worried about borrowing contaminated books from your own library, you can always call first to find out what safety guidelines they’re following. Or, you could stick to e-books for a while—here are five free ways to get them.
