This paper reviews resource sharing on three levels: (1) Singapore, (2) jointly with Malaysia, and (3) Southeast Asia. Topics covered include staff training, cooperative acquisition, bibliographical projects, the Cooperative Microfilming Program, the Microfilm Clearing House, and the proposed Consortium of National Libraries and Documentation Centers for Southeast Asia. Conclusions indicate that Singapore enjoys good cooperation among libraries, and with links and contacts established with Malaysian and ASEAN neighbors, resource sharing will become a matter of course in the area.
