Tess is out of control and roaring—in the library, of all places—so her mother gives her a time out. Yoshikawa's colorful mixed-media illustrations on a soft yellow background show Tess, frustrated, leaning against a shelf and accidentally knocking it over. Now it's not Tess roaring but a T. Rex, who has escaped from one of the fallen books. As the dinosaur runs amok with Tess on his back, other characters and subjects from the books—knights, fish, pirates, cowboys, planets—rise up. T. Rex's rowdy behavior begins to concern Tess, and she starts to worry about the books themselves. When the dinosaur piles up books and climbs on them, Tess notices they are ripping, and, taking control, she gives T. Rex a well-deserved time out himself, pressing him back inside his volume. A lively introduction to the multitude of stories and topics found in a library with an emphasis on the importance of book care and library etiquette, this will especially appeal to active youngsters. Good for home, classroom and library use. (Picture book. 3-6)

PreS-K Free an excitable beastie in a library and shelves will fall, pages will rip, and books will be chewed. After a fun, but slightly wild ride through the different sections of the building, Tess sees the need to get T. rex back into his book. But can she do it without saying goodbye forever? Luckily, she has the rules fresh in her mind, and the skills to keep a dinosaur in check. When reading Tess and T. rex's story, the roars, snarls, and snorts will need to be delivered in full force. Youngsters can also use their stern parental voice to say "Watch out!" "Time out!" and "Be careful!" and give commands like "Charge on" and "Yee-haw!" Buzzeo and Yoshikawa make it obvious how children are supposed to behave in a library while giving sneak peeks at some of the different sections and exciting possibilities that they might encounter on a visit. Mixed-media illustrations have loud colors, quick movements, and costume changes to match the section of the library. Although this book is lively at the start, it does have a calm ending consisting of a hug and a whisper. Offer this one to children who enjoy Jane Yolen's "How Do Dinosaurs" series (Scholastic).
