Two California bookstores in Napa Valley saw books fly off the shelves early Sunday morning, but not in the usual way. A magnitude 6.0 earthquake sent them tumbling and kept Copperfield’s Books in Napa and Napa Bookmine closed on August 24.

Neither store suffered structural damage. “But it’s a big fat mess,” Copperfield’s store manager Lindsay McConnell told SFGate. Seventy percent of the books were on the floor along with mugs, candles, and jars.

Napa Bookmine offered a video of the extent of the damage on its Facebook page, where it noted that it has some “seriously helpful volunteers” putting the store back together. Thanks to them the bookstore will be open its regular Monday hours, starting at 10a.m. on August 25.
