Starting June 1, 2003, the Library of Congress will cease adding copyright registration numbers in field 017 to bibliographic records created by the Geography and Map Division. This affects records distributed via MDS-Maps. The Division has decided to discontinue using field 017 to cut cataloging costs and because the field is not accessed by the Geography and Map Division staff. It appears that the impact on outside agencies will be minimal.
Records from outside cataloging agencies that contain field 017 will continue to be accepted and distributed via MDS-Maps.
