DUALabs
From Wikipedia, the free encyclopedia
DUALabs (National Data Use and Access Laboratories) was the name of an American company whose proprietary compression algorithm was used to compress the 1960 and 1970 census data under NSF grant 7249358 to the Center for Research Libraries. DUALabs also received funding for the project from the Ford Foundation and NICHD (Contract 72-2707).
The company was headed by former Census Bureau employee Jack Beresford (1931-1996), who had worked on the compilation of the 1960 census, and the company headquarters was in Rosslyn, Virginia.
DUALabs declared bankruptcy in the early 1980's, and the remaining decompression software will only run on obsolete hardware. The University of Pennsylvania's Population Studies Center now features updated decompresion software for DUALabs' data sets written in Perl[1].
