The document outlines rules for alphabetic filing and indexing of records. It discusses indexing the key units in personal names by surname, given name, and middle initial. For business names, each word is a separate unit indexed as written. Minor words like articles and prepositions are separate units. Punctuation is disregarded. Initials and abbreviations are treated as single units. Cross-referencing is used for unusual names, hyphenated surnames, alternate names, and similar names to aid retrieval.
