- TM=Topical Module
- TMR=Topical Module Research ( see the usernote regarding Research files )
- FP=Full Panel/Longitudnal
- PLC=Panel Longitudnal Core ( The 1996 Panel Longitudnal Core files are BLS cleaned and edited versions of the Core files. So use PLC files rather then Core files. They replace the Full Panel files created for earlier panel years ).
- RT=Core (Rectangular) and Topical Module
- IB=Information "Booklet" (1989-1991 file is 570 pages, 27Mb).
- RW=Replicate Weight
- orig=Some waves have multiple topical modules. BLS released each topic when it was ready as 'x', 'y', 'z' files. Later, BLS re-released the files in a single topical module file when all were ready.
The Census Bureau did not produce a Full Panel file for 1989. The last wave in the 1989 panel is Wave 3. 1989 wave 2 topical modules were never processed or released. 1993 is the last year the Census Bureau produced a full panel file.
- The 1996 Panel Longitudinal Core files are cleaned, edited versions of the Core files. So, use the PLC files rather than the core files.
- The BLS published a user note regarding the 1996 Panel Longitudinal Weight Adjustment Factor on October 14, 2005.

The 2001 Longitudinal weight ( lw9 ) files were replaced per BLS update May 6, 2005. Replace files if accessed prior to May 6, 2005.
The BLS releases files, and even single topics of topical module files, as soon as they are ready for release. This means that a file that was fielded earlier may not be released until after the release of a file that was fielded later but finished preparation earlier.This also means that if a topical module has multiple topics, the BLS may release the completed parts of the topical module as soon as they are ready rather than waiting for all topical modules fielded in the same month/wave to be completely processed.These single topics of topical modules are named 'x', 'y', and 'z'.When all the topics of a wave are completed, BLS re-releases a topical module file which includes all the topics for the topical module in a single file with just a plain, number. It is terrific that the BLS releases files as soon as they are ready rather than waiting.
