These are representative questions of some of the desires for books that children express to the ICDL, and its on-line presence is organized and searchable in a way that can help meet such demands. Observing that children are not well served by most existing dictionaries, Bederson and his colleagues use definitions from children themselves, and then enable children to rate each other's definitions. By incorporating teams of children into all stages of the design and development of the various component parts of the library, the ICDL team is able to be guided by what children want, and how children act. Given the strong research focus of project principals, findings from the ICDL experience are being well documented and made publicly available.
