Many of Eleanor’s books and papers, a large collection of video records, and much of her students’ work has been relocated to the CEPress office. These materials are being organized and their titles and descriptors recorded on spreadsheets in order to facilitate their access and use and, in the case of student work, potential publication.
Yang's library of printed and manuscript educational works is held at CEP. Published materials include over 130 books on education, children's learning, writings of Galileo, Dewey, Piaget, as well as printed articles from education course readers at Harvard Graduate School of Education. The manuscript collection of Yang's works includes about 200 items in English and Chinese.
The CEPress office also contains a library of books and other materials related to the work of Critical Exploration in the Classroom, particularly in the areas of progressive educational theory, Piagetian method and theory, and progressive curricular development. For example, CEPress is currently working to assemble full sets of the Elementary Science Study and the African Primary Science Project.
