Bookstores have stepped in to help those affected by the deadly Wine Country wildfires that have destroyed thousands of structures, forced tens of thousands from their homes and left many others without power.

Copperfield’s Books, the independent Bay Area bookstore chain, closed two of its eight locations, in Napa and Calistoga. But its other stores — in Petaluma, Sebastopol, Novato, Montgomery Village, Healdsburg and San Rafael — are providing patrons with free Wi-Fi, charging stations for phones, and the use of restrooms. The stores are also welcoming customers with dogs.

“There’s always a safety net in bookstores, I believe,” said Mimi Figlin, Copperfield’s general manager. “We’re here for the community.”

“The landscape of our home may have changed,” Copperfield’s wrote on Facebook, “but we will not abandon it, we will rebuild and get through these trying times together.”

[Update: Copperfield’s store in Napa has reopened.]

Point Reyes Books, in Point Reyes Station, said that it will donate all profits from sales, Oct. 13-15, to a community fund sponsored by the Redwood Credit Union.

[Update: Point Reyes Books has raised roughly $2,000 for the fund. The money, said the store’s co-owner, Stephen Sparks, includes tips collected by Laura Scott, an employee at the adjoining Bovine Bakery. “It’s a little drop in the bucket,” Sparks said, “but we know it’ll be put to good use.”]

Copperfield’s is also helping the same community fund: Donations from a free “Jazz in the Neighborhood” benefit will go to relief efforts. The event will be held at Copperfield’s’ San Rafael store at 6 p.m. Friday.

Readers’ Books in downtown Sonoma, was asked to evacuate; the store said it would remain closed until further notice.

“We want to be here for people who need a place to go,” said the store’s buyer, Jude Sales, before closing the store earlier in the week. “We feel like we want to do something — if nothing else, we want to be a safe place for people.”

Napa Bookmine, which had closed both its stores in Napa, reopened Friday.

Treehorn Books, on 4th Street in downtown Santa Rosa, opened Tuesday after being closed Monday.

“I feel so bad for the community,” said store manager Grant Hotaling, “and if there’s anything I can do at all, it’s to open the store and offer a place for people to come in and perhaps take their minds off their troubles.”
