Provided for teachers and the general adult reader is an annotated and graded list of books and reference materials dealing with aerospace subjects. Only non-fiction books and pamphlets that need to be purchased from commercial or government sources are included. Free industrial materials and educational aids are not included because they tend to have a transitory availability. Books and reference materials are listed, alphabetically by author, in the subject matter index (part 1). Major subject areas are: space exploration; impacts of space exploration; future space activities; astronomy; exobiology (life beyond earth); aeronautics; energy; space and the humanities; and aerospace education. Suggested reading/usage levels, designated by codes, are also provided in part 1. Codes include P-primary (grades 1-3), I-intermediate (grades 4-6), U-upper (grades 7-8), S-secondary (grades 9-12), and U-adult/college level. Most books of general interest to the public at the adult level are also listed for secondary. Part 2 contains an annotated list, arranged alphabetically by author, of all books/materials cited in the subject index. Author(s), title, source, number of pages, International Standard Book Number (ISBN), and annotation are provided for each entry. Likewise, the same information is provided for reference materials (guides, annuals, atlases, bibliographies, dictionaries, and encyclopedias) in part 3. (JN)
