BOOK DRIVIN'

Imagine this: You're standing in line at a food truck for lunch when you glance over and notice an 18-wheel tractor-trailer that's not serving food but, yes, library service. That's right, you just encountered the Digital Bookmobile.

In town in time for the National Book Festival this weekend (and next), kids can learn how to download audiobooks from their local library at interactive learning stations inside the 74-foot-long vehicle, and adults can score through its extensive digital media collection, sample audiobooks and use supported mobile devices.

This community outreach vehicle has served communities for decades. It is owned by OverDrive, which provides audio downloads for more than 18,000 libraries worldwide. It will be stationed on the National Mall (950 Independence Ave. SW) on Sunday from noon to 5:30 p.m.

D.C.'s TOP CHEF

It's safe to say the District is home to some crazy talented, Food Network-worthy chefs. Mike Isabella, fierce "Top Chef" competitor and owner of the D.C.-based Italian eatery Graffiato, is no exception. Lucky for us, Isabella is about to release his first cookbook, "Crazy Good Italian." Be the first to snag a signed copy at Graffiato (707 Sixth St. NW) from 11:30 a.m. to 2 p.m.

The cookbook contains a whopping 200 recipes inspired by the cooking of his Italian-American grandmother. These everyday meals are "small plate" versions of Mediterranean classics. You'll even recognize some of the recipes that launched his stardom on "Top Chef."

There are no signs of slowing down for this celebrity chef. Isabella plans to open two new restaurants in the District next year.
