A discussion piece to assist the U.S. Bureau of the Census in planning for the effective use and dissemination of future census data and products in the Government Printing Office's Depository Library Program (DLP), this report identifies key issues that may affect the role of the DLP in providing the public with access to Census Bureau data. The report discusses likely trends that will affect the effectiveness with which the DLP provides access to Census Bureau services, and describes a range of possible scenarios for the dissemination of Census Bureau data and services that will influence the DLP. A concise descriptive listing of key issues and policy questions that require debate and discussion in the professional community is provided. The report focuses on eight issue areas: (1) future technologies for exploiting Census Bureau data; (2) the rate of absorption of new technologies by depository libraries; (3) space considerations for storing Census documents over time; (4) use of paper as a preferred medium for the data; (5) use of other media as storage devices; (6) how the structure of the DLP may affect the dissemination of Census data; (7) trends in the usage of Census data; and (8) the feasibility of more research in the patterns of use of the data. Appended materials include a questionnaire used at a meeting of the Depository Library Council to the Public Printer and a paper, "Future Information Technology and Dissemination Trends: A Literature Search and Analysis" (Nancy R. Preston). (6 figures; 88 references) (SD)
