    Abstract
    Indexing terms supplied by authors can increase subject control of their documents. The terms can be used in the creation of indexes, abstracts, and other devices for information retrieval in the special library. An examination of the American Mathematical Society author indexing program suggests that contributions of authors enhance indexing efforts of editors
