All ECLS-K data are released in CD-ROM format. The CD-ROMs include the data files, electronic codebooks (ECB), user's manuals, the survey instruments, and the record layouts. The ECB can be used to 1) examine variables in a data set, 2) examine question wording, response categories and frequency distributions, and 3) select and export variables along with the appropriate code needed to create SAS, SPSS-PC, and STATA datasets.
