Establishing Program for Cooperative Cataloging (PCC) Chinese Japanese Korean (CJK) NACO, BIBCO, CONSER, and SACO funnels grew out of the PCC’s strategy of engaging and inclusion of diverse membership, and the commitment of the Council on East Asian Libraries (CEAL) to collaboration with PCC, the Library of Congress, and the American Library Association. Together, PCC CJK funnels and CEAL’s Committee on Technical Processing (CTP) have been taking leadership roles in contributing quality metadata, developing CJK-specific training programs, participating in the development of PCC policies and best practices, and engaging in international collaborations. This article discusses challenges the CJK funnels and CEAL CTP have faced and strategies taken in this ongoing collaborative endeavor.
