NEW ORLEANS — The Community Book Center, a longtime fixture on Bayou Road, was one of the numerous small-business casualties of Hurricane Katrina. The storm ravaged the venture that Vera Warren-Williams had nurtured for 25 years, where she sold black novels, school texts, gifts and artwork.

The windows blew out, the roof was ripped and at least two feet of water sat inside for several days, resulting in about $250,000 worth of structural damage and loss of inventory.

The owner's insurance wasn't nearly enough to cover the devastation, and she didn't have flood coverage.

"You know you have to come back," Warren-Williams said. "But when you looked at the devastation, you weren't quite sure how."

Help arrived in the form of a group of Stanford University MBA students and their ideas.

With the assistance of the Idea Village, a nonprofit that has provided scores of local businesses with technical support, contacts and capital, the students — 15 in all — have adopted several enterprises, among them the Community Book Center. Their mission is to help these businesses find ways to grow and survive in post-Katrina New Orleans.

The storm physically destroyed or financially hurt more than 80 percent of the 12,695 small businesses that were in Orleans Parish before Katrina, according to local business officials. The few that have reopened are struggling to stay afloat with fewer customers, reduced profits and higher labor costs.

The MBA students believe they can help. "Education is what you learn in the classroom," said Daryn Dodson, 27, who organized the student group. "It doesn't mean anything until you apply it practically."

Dodson began his master's program the week Katrina battered New Orleans. As he sat in his dorm room, watching the disaster unfold on television, he felt compelled to do something.

He started fundraising drives, including a "gumbo get-together," where he and fellow students raised about $7,000 and donated it to Habitat for Humanity.

"We sent the check, but it felt so empty," Dodson recalled.

In December 2005, during winter break, he took his first trip to New Orleans, seeing what help was needed. On spring break, he was back with two dozen other Stanford students helping gut flood-damaged homes.

The most recent trip, Dodson's fourth, brought him and fellow Stanford MBA students Sarah Chandler Mallari, Shara Tortora and Eugene Baah to the Community Book Center.

For Warren-Williams, it wasn't a moment too soon.

Student volunteers had helped her clean and gut the store after the storm. Other volunteers tackled the mold while her husband's cousin, a contractor, fixed the roof. Residents, customers and local groups donated plywood, paint and other materials. The Idea Village provided technical assistance and a $5,000 grant, which Warren-Williams said she used to replace inventory.

Now Dodson and his group are helping her tap into the remaining customer base, for which all the surviving neighborhood businesses compete, and get the dollars flowing.

Warren-Williams said her store had operated more like a community service center than a moneymaking venture. "The bottom line has not necessarily been profits but just providing a service," she said.

But with about 75 percent of her customer base gone, things had to change.

This week, Dodson and his team met with Warren-Williams in the rear courtyard of the Community Book Center, which reopened in December but closed again recently for further renovation.

The Stanford team presented Warren-Williams with several recommendations, including erecting a sign at the end of her street to catch the eye of motorists and pedestrians on the adjoining thoroughfare.

They also proposed that Warren-Williams use a "drop bowl" for business cards and a store guestbook to get customers' mail addresses for special programs.

The store is six blocks from the Fair Grounds, site of the Jazz and Heritage Festival, and the MBAs suggested that Warren-Williams seek permission to advertise there and recruit a "street team" of neighborhood kids to place fliers on cars.

Other recommendations included displaying books and artwork on the sidewalk in front of the store, placing pamphlets in neighboring businesses and setting up a coffee shop and a photocopy-print-and-fax center that someone else would lease from Warren-Williams and run.
