As developed by the nonprofessional staff of St. Michael's College Library, Basic Rules of Alphabetic Sequence Simplified (BRASS) is a refined system of alphabetic filing for library card catalogs. It is designed to be a concise set of principles, consistently applied, making it therefore faster than other standard filing systems. BRASS consists of 12 rules, each illustrated by specific examples. Rules cover basic alphabetization, including foreign words, numerals, abbreviations, and acronyms; interfiling of types of entries; variant spellings; subfiling of identical entries, added entries, and multiple editions; and filing of cross references.
