Since 1992 Library of Congress Rule Interpretations (LCRI) has been formulated by the Cataloging Policy and Support Office (CPSO), the successor to the Office for Descriptive Cataloging Policy.  The text of the second edition of the looseleaf service includes all valid LCRI issued through June 2002 (Update no. 2, 2002).  The rule numbers used are those found in the Anglo-American Cataloguing Rules, second edition, 2002 revision.  Library of Congress catalogers will begin to apply the 2002 revision on December 1, 2002.

The formulation of LCRIs at the Library of Congress follows a process in which drafts are written in CPSO and then circulated to Library of Congress staff for comments.  These drafts are also distributed, when appropriate, to participants in the Program for Cooperative Cataloging (PCC).  The published versions then are the product of a diffuse authorship, both for substance and for wording.  As a result of this process, the glosses LC practice, PCC practice, or LC/PCC practice are used to distinguish practices of these organizations from general national practice (see Introduction for fuller information).  Note that PCC practice replaces both NACO practice and CONSER practice.
