SCRIPPS HOWARD
Lovers of children's books are in high gear these days, wondering which books will win the 2007 Newbery and Caldecott medals tomorrow.
Deliberations by the awards committees are cloaked in secrecy. Yet there are some obvious favorites for the Caldecott Medal, presented to the best-illustrated children's book, and for the Newbery Medal, given for the best-written children's book.
The following list is drawn from several sources, including recommendations by several children's book experts: Anita Silvey, author of "500 Best Books for Teens;" children's literature consultant Amy Kellman; Micki Freeny, director of the Prince George's County, Md., Memorial Library System; and children's literature consultant and teacher Maria Salvadore.
Of course, there are always surprises. A mock Newbery group run by librarian Nina Lindsay, for example, just chose a surprise winner --"A Drowned Maiden's Hair" (Candlewick, 15) by Laura Amy Schlitz.
