Two-time Caldecott Medalists Leo and Diane Dillon team up with Margaret Wise Brown in Two Little Trains, first published in 1949. Right from the cover, the sleek, horizontal illustrations chronicle the parallel journeys of the titular trains: a toy train wrapped in a gift box waits on the platform next to a massive modern train. "One little train was a streamlined train,/ Puff, Puff, Puff to the West./ One little train was a little old train,/ Chug, Chug, Chug going West." In one spread, the trains look down at the "deep dark river." The streamlined train races across a purple bridge while, opposite, the toy train crawls along the edge of a bathtub, the purple soap and tub basin connecting the tub scene to that of the locomotive.

Restful and happy scenes of Emily's father caring for her while she's under the weather play up the gentle humor and tender tone of the text. When she is feeling better, their roles reverse, and Emily takes care of her ailing father.

The white kitten of the title, boldly outlined in black line, grows and frolics through the seasons. In autumn, as leaves fall "slowly to the ground," the text mimics their movement. (Golden, $14.99 48p ages 2-5 ISBN 0-307-20203-8; June) Trina Schart Hyman fans will be glad to know that Rapunzel, retold by Barbara Rogasky, originally published in 1982, is back in print. The artist frames her dark and dramatic full-page and vignette illustrations in repeated pattern borders, and evokes the detailing and care of quiltmaking as she pieces together the images of this classic story. (Holiday, $16.95 32p ages 4-8 ISBN 0-8234-0454-4; May) Winner of both the Coretta Scott King Author Award and the Coretta Scott King Illustrator Award, Ray Charles by Sharon Bell Mathis, illus. by George Ford, originally published in 1973, traces the star's surmounting of incredible obstacles to become one of the world's greatest jazz musicians. Ford's illustrations capture every emotional nuance, from Ray's disappointment at being tricked by classmates as a child, to his strength as a man, refusing to perform to segregated audiences.

Following up on last fall's reissue of Harriet the Spy by Louise Fitzhugh, Delacorte is reissuing two continuing adventures featuring Harriet and her gang. In The Long Secret (1965), Harriet becomes intent on uncovering the identity of the person who is penning anonymous proverb-like notes all over town that betray a keen insight into the addressees. Money isn't everything, as Harriet's best friend learns in Sport (1979). After Sport's grandfather dies, leaving him millions of dollars, greed draws out Sport's mother, who kidnaps him. How can Sport return to life as it was before? (Delacorte, $15.95 each ages 10-up ISBN 0-385-32784-6; -32785-4; May)

The Most Interesting Book You'll Ever Read About Memory, both by Diane Swanson, illus. by Rose Cowles. In Burp! Swanson explains the functions of the human body parts using a combination of facts ("Your stomach is a J-shaped elastic sac that can stretch to hold about 1.5 L [1½ qt.] of food"), anecdotes ("Boiled briefcases, lipstick, sawdust and plaster made for bizarre food in 1941, when war trapped 3 million starving people in Leningrad, Russia") and child-oriented experiments.
