This bibliography on informal education grew out of a concern to understand the kinds of programs possible in open plan schools. The annotations are reading notes generally more descriptive than evaluative. Citations are grouped under nine headings: (1) general, (2) description of British informal education by British writers, (3) description of British informal education by American writers, (4) description of American informal education by American writers, (5) methodology for informal education, (6) teacher education for informal education, (7) criticism of informal education, (8) research and evaluation of informal education, and (9) bibliographies on informal education.
