Regulation is divided into "parts" and each part is divided into "subparts." In the CFR system, the CFR section is the basic unit of text. In the NASA PR, the paragraph is the basic unit of text.

Within the text of a NASA PR paragraph, there is not a uniform numbering system for the subdivision of text as there is for text within CFR sections. However, most NASA PR paragraphs are consistent within themselves. Users are advised, therefore, to be alert for codification variations in numbering within NASA PR paragraphs.

METHOD OF UPDATING NASA PROCUREMENT REGULATION

The regulations in these CFR volumes include the text of the 1977 NASA Procurement Regulation updated by the incorporation of amendments in NASA Procurement Regulation Directives (PRD's) through PRD 78-10, July 31, 1978. Volume III also includes an Appendix containing those PRD's which are outstanding and still in effect but which have not been incorporated. For a list of these outstanding PRD's, see the List of Sections Affected by Unincorporated PRD's in the Finding Aids section of each volume. Hereafter, all amendments to the 1978 edition of 41 CFR Chapter 18 will be accomplished by full text publication in the Federal Register. (See 43 FR 40018, September 8, 1978.)

PAGINATION

Each of the three volumes is individually paginated. The page number is centered at the bottom of each page.

The following information should be of use to those users who are familiar with NASA PR replacement page technique for updating the regulations. The upper left corner (for even pages) and the upper right corner (for odd pages) contain pagination information for each section of the part. These page identifiers begin numbering anew with each part. A typical reference might be "1-2:3”. The number to the left of the dash refers to the NASA PR part. In this case, the "1" refers to "Part 1." The number to the right of the dash refers to the NASA PR subpart and the number to the right of the colon refers to the page of that NASA PR subpart. Thus, the reference "1-2:3" indicates that the user has page 3 of Subpart 2 of Part 1.

TABLE OF NASA PR PARTS AND SUBPARTS

Each volume has a complete table of contents listing of all the NASA PR parts, appendices, and supplements contained in the three volumes.

Each of the three volumes also has a table of contents listing the parts contained in that particular volume and the page where each part (or appendix) begins. This table appears on page 3 of each volume.

The Code of Federal Regulations is published under the direction of Martha B. Girard, assisted by Pearl B. Einhorn. The editors of this volume were Margaret M. Donohoe and Robert D. Fox.

NOTE: Since the NASA PR has been incorporated directly into the Code of Federal Regulations, the volumes themselves are the sole permanent source of research material. Subscribers may wish to retain these volumes for their future

use.
