Helping the user retrieve data from a CD-ROM

In January, 1991 the National Center for Health Statistics (NCHS) distributed their first CD-ROM. On this CD-ROM, the NCHS released 1987 data from one of the oldest national health surveys, the National Health Interview Survey (NHIS). The NHIS is a principal source of information on the health of the population of the U.S. The 1987 NHIS CDROM contains nine data files with over 300,000 encoded records as well as documentation, help information, and search software called SETS (Statistical Export and Tabulation System).
