Sec. 1-7.  Supplementation of Code.
(a)   Supplements to this Code shall be prepared and printed whenever authorized or directed by the city. A supplement to this Code shall include all substantive permanent and general parts of ordinances adopted during the period covered by the supplement and all changes made by the supplement in the Code. The pages of the supplement shall be so numbered that they will fit properly into the Code and will, where necessary, replace pages that have become obsolete or partially obsolete. The new pages shall be so prepared that when they have been inserted, the Code will be current through the date of the adoption of the latest ordinance included in the supplement.
(b)   In preparing a supplement to this Code, all portions of the Code that have been repealed shall be excluded from the Code by their omission from reprinted pages.
(c)   When preparing a supplement to this Code, the person authorized to prepare the supplement may make formal, nonsubstantive changes in ordinances included in the supplement, insofar as necessary to do so in order to embody them into a unified code. For example, the person may:
   (1)   Arrange the material into appropriate organizational units.
   (2)   Supply appropriate catchlines, headings and titles for chapters, articles, divisions, subdivisions and sections to be included in the Code and make changes in any such catchlines, headings and titles or in any such catchlines, headings and titles already in the Code.
   (3)   Assign appropriate numbers to chapters, articles, divisions, subdivisions and sections to be added to the Code.
   (4)   Where necessary to accommodate new material, change existing numbers assigned to chapters, articles, divisions, subdivisions or sections.
   (5)   Change the words "this ordinance" or similar words to "this chapter," "this article," "this division," "this subdivision," "this section" or "sections ________ to ________" (inserting section numbers to indicate the sections of the Code that embody the substantive sections of the ordinance incorporated in the Code).
   (6)   Make other nonsubstantive changes necessary to preserve the original meaning of the ordinances inserted in the Code.
