Union list development: control of the serial literature

The discussion covers the development of a national union list or finding tool for biomedical serial holdings and its integration into the National Serials Data Program, which is being developed under the auspices of the three National Libraries. Specific topics which are covered include: (1) Selection of the Union Catalog of Medical Periodicals (UCMP) as the basis for a biomedical list and the status of that activity; (2) discussion of the various methods of recording holdings; (3) status of the National Serials Data Program and a discussion of its relationship to the UCMP file; and (4) status of the Standard Serial Number and its relationship to other existing coding schemes for serial titles.
