2.12.-2.18. Early Printed Monographs

The Library of Congress will not apply these rules. Instead, for any book published before 1801, it uses, effective July 1, 1991, Descriptive Cataloging of Rare Books. (Before July 1, 1991, it used Bibliographic Description of Rare Books.) For books published after 1800 it applies 2.0-2.11.
