The audience will be public education teachers. There is a a sort of educational reform going on. I say sort of because this has not been a planned reform but one that has been constructed on the way. Teachers and directors are supposed to be the principal engines in this reform. Teachers have 40 or more students per class.
Teachers are underpayed.
Generally they have not received any training in library work. I do know the main requirements these teachers need. I have been doing research in school libraries in Peru for some years now. What I want you to help me with is a general idea, or metaphor to work with. Something that will interest them.
