[List of CFR Sections Affected (LSA), 1986-2000, Volume IV (Titles 42 through 50)] [From the U.S. Government Printing Office, www.gpo.gov] EXPLANATION OF THIS VOLUME GENERAL This Volume IV contains a compilation of the ``List of CFR Sections Affected'' (LSA) for Titles 42 through 50 of the Code of Federal Regulations (CFR) for the years 1986 through 2000 (Titles 1 through 41 appear in Volumes I, II, and III.). All sections of the CFR which have been expressly affected by documents published in the daily Federal Register during those years are listed. Entries indicate the nature of the changes effected. Page numbers refer to daily Federal Register pages. The volume number appearing at the beginning of each column indicates the year (for example, 51 FR corresponds to 1986, 52 FR corresponds to 1987). Reorganization, redesignation, and distribution tables for certain titles appear at the end of the LSA for that title. Specific references to these tables appear within the text of the LSA. USE Reference to this LSA will enable the user to find the precise text of CFR provisions which were in force and effect on any given date during the period covered. To determine the history of a section of any regulation, the user must first look for that section under the pertinent CFR title. Within each title, the entries are arranged chronologically so that all 1986 amendments precede 1987 amendments, and so forth. In addition to the specific section level entries, the user is cautioned to check for general changes that may appear at the title, chapter, and part levels.
