Children's book publishers, agents, authors, and artists from around the world descended on Bologna, Italy, this week for the 51st annual Bologna Children's Book Fair. While official attendance figures aren't yet available, program director Roberta Chinni told PW that she was "very happy" with attendance and that the publishers she had spoken with were pleased with the number of appointments and overall energy of the fair.
