Ms. Osborne served two separate terms as president of the Authors Guild and also chaired its Children's Book Committee. She has since traveled extensively in the states and throughout the world, visiting schools and speaking on issues related to reading and books. In 2011, she attended the International Tokyo Film Festival for the premier of the Magic Tree House anime film and visited schools in the tsunami-hit area of Japan. The film grossed 5.7 million dollars; Osborne donated all her proceeds into her educational works.
