"The consortium for International Earth Sciences Information Network (CIESIN), in conjunction with the Urban Information Center at the University of Missouri St. Louis has established a public archive of United States census data. The data are available via the Internet using FTP and/or a WWW browser. Currently the archive contains map boundary files for all common geographic units used in the census (including census blocks, block groups, tracts, counties, etc.) in a standard ASCII (BNA) format. Data extracted from the 1990 decennial census Summary Tape File 3 (STF3) are provided in a format that makes it easy to link with the boundary files to create thematic maps with widely available GIS software such as Atlas GIS, ArcView and MapInfo. These data files are organized by state and geographic level.... This paper discusses the content of the archive as well as describing some of the details of how and why it was constructed."

The increasing availability of official national statistics in France in CDROM format is examined on the occasion of the publication of the 1999 edition of the Tableaux de l' Economie Française [Tables on the French Economy] in this format. The author describes the various ways in which data in CDROM format can be accessed and used for educational purposes in ways that are not possible if these data are only published in hard-copy format.

65:41663 Musgrave, Simon. Making data visible: an introduction to the NESSTAR client software. Data Archive Bulletin, No. 72, Sep 1999. 1-7 pp. Colchester, England. In Eng.
This article is an introduction to the NESSTAR (Networked European Social Science Tools) Project and the beta version of its client software. "NESSTAR is [a] joint development of the UK Data Archive, the Norwegian Social Science Data Service and the Danish Data Archive. It has been funded by the IVth framework programme of [the] European Union, under the Information Engineering programme. The application will enable the leading social science data archives, and other data publishers, to provide radically enhanced on-line services. [NESSTAR is] a seamlessly integrated data discovery, analysis and dissemination system based on Java technology and a newly developed metadata standard expressed as an XML-DTD.... NESSTAR might be described as a virtual data library offering global access to locally supported holdings." A CD-ROM of the Beta 2 version of the NESSTAR Explorer software is included with this issue. The latest version can be downloaded from www.nesstar.org.

This special issue is concerned with the Integrated Public Use Microdata Series (IPUMS), a coherent national data base describing the characteristics of 55 million Americans in 13 census years spanning the period from 1850 through 1990. The "introduction provides a short history of the ongoing IPUMS project, where it stands at present, new features and improvements added since our 1995 release, and what we hope to accomplish in the next few years. Separate articles describe the IPUMS documentation and data extraction system in detail. Additional articles discuss procedures for creating new historical census samples at the University of Minnesota. Topics include the new 1860 and 1870 census samples, the 1910 Black and Hispanic Oversamples, our evolving procedures for interpreting census manuscript responses, and techniques for identifying metropolitan areas."
