You can define a section prefix to label section pages automatically. For example, if you specify A– for Section Prefix on page 16 of a document and include the section prefix, the page will appear in the table of contents or index as A–16. Text you type for a section marker appears when you choose Type > Insert Special Character > Markers > Section Marker.
The values for Number position (here called Aligned at), Text indent and Follow number with are in the Position section at the bottom. With multi-level numbering, you also have easy access to settings that control the type of numbering at each level, the characters before and after each level’s numbers (period versus parenthesis), and the list number style (1, a, I, etc.).
I want to point out that if this document is a fixed set of standards but will be amended in later editions, then autonumbers will increment, which is a bad idea. In legal documents, numbers are usually static, and deletions are struck-through, not deleted, to preserve the original numbering, so that older and newer editions can be compared number-by-number. Inserted and appended content would need to be manually numbered. You may want to create the first edition with autonumbering, then convert the numbered list numbers to text, to avoid unwanted renumbering in future editions.
If the list you want is as simple as "1", "2", "3", you'll appreciate how easy it is to apply this type of numbering in legal documents. Simple numbered lists are different in Word 2000 than they were in Word 97. In Word 2000, the default for even the most basic list is multi-level. For example, if you number an item and press Enter and then press the TAB key, Word automatically formats this number as the second level in an outline numbered list format. Single and multi-level numbering are explained later in this chapter.
A best practice that we recommend to our clients is to create a base/folio master –with styled and positioned footers and current page number special characters– on which all other masters are based. This allows a footer that may contain date or issue information to be updated once and the changes are reflected in all of the master pages. If your masters only have current page number special characters then you can just add them to each master and the page numbers will be reflected when each master is applied to your document pages. document numbering in indesign
