With support from the Bureau of the Census, Lawrence Berkeley National Laboratory (LBNL) has completed tasks to provide Internet access to historical Census data. Data from the 1940's through the 1980's are in a legacy system previously at LBNL, known as SEEDIS. In 1996-97 SEEDIS was transferred to an internal computer at the Bureau of the Census.

waiting for data extraction
A small (16 MB) subset of SEEDIS (1980 Summary Tape File 3 for counties and states) is presently available for Internet access, with low-level access routines written in C. Programmers can use the software provided to extract data of interest. A Web user interface is not available,
The complete SEEDIS system, with about 15 GB of data, was previously available on seedis.lbl.gov, a Digital VAX computer at Lawrence Berkeley National Laboratory (LBNL). In 1996/97, SEEDIS was transferred to seedis.census.gov, a internal VAX computer at the Bureau of the Census.
file systems on seedis.census.gov (for internal use)
The VAX-based system at the Census Bureau is accessible via telnet. However, because documentation is incomplete and because current funding does not provide for user support, SEEDIS is not available for public access. Agencies wishing to obtain private access may contact Valerie Gregg at the Bureau of the Census.
In the future, the SEEDIS data, including 1960, 1970, and 1980 Census data and other historical data, will incorporated into Web-based systems now being constructed at the Bureau of the Census.
