"Structure of the bibliography. Entries are chronologically arranged. Within the major divisions by decades, each year is divided into two sections: 'books, monographs and catalogues' and 'journals'. Each section is set out alphabetically by the surname of the author (if known), while anonymous items are located at the end of the section, arranged alphabetically by title of book or journal. There is a continuous numbering sequence from 001 to the end, the entry numbers being cross-referenced to an index of individual works and an index of personal names."--Page ix.
