Information on the 48 courses, workshops, seminars, and other educational opportunities listed in this guide was gathered by questionnaires sent to schools of library and/or information science and organizations sponsoring training opportunities in indexing in the United States and Canada. The definition of indexing used is broad: it includes indexing of collections, monographs, periodicals and other serials, and parts of documents; subjects, authors, titles, and any other characteristic of information and documents of interest to potential users; the creation of both alphabetically arranged indexes and systematically arranged classifications; and both automatic indexing based on computer manipulation of textual symbols and human intellectual identification of content. The guide includes a listing of textbooks used in indexing courses, a classification of indexing concepts and procedures, an alphabetical index to this classification, a classified index to indexing concepts and procedures covered in courses, workshops, and seminars; descriptions of indexing courses, workshops, and seminars; and an index to courses by state or province and city.
