Each document in your book can be numbered, and these numbers can be used as automatic chapter numbers. Automatic will increment from the previous document’s number, or you can choose “Same as Previous in Book” if it’s still the same chapter but broken into two or more parts, or you can arbitrarily number it anything you want to. This can save time if you have a large number of chapters that change order frequently, since the numbers will update automatically.

Thanks for the head start on this, it got me part the way through my problem but I found that when I had 3 figures in a row then a map, the next figure would jump back to #.1 again. Because I had figures, maps and tables that needed to be numbered I used the ‘levels’ to differentiate between them as you suggested, but found if you create a new number list for each entry ie. number list for maps, and number list for tables etc then they don’t conflict. thanks for the start off though. no where else pointed it out as clearly as this. Cheers
There are lots of options. For instance, you might reduce the amount of space between the number and the text by changing the Text indent at setting. Or, you might center the heading by choosing Center from the Number alignment dropdown. For even more options, click More to expose several more settings. You could use the Apply changes to option when setting level 1 to the I, II, III numbering style instead of changing it for each level.
You can control whether your next paragraph number continues the current sequence or starts again at 1 within that same right-click menu. If one of your numbers gets out of sequence, simply right-click and choose Continue Numbering. If you want to force the number back to the beginning (say, you’re switching from interrogatories to requests for production), choose Set Numbering Value (which will also give you the option of continuing the previous list).

Understanding outline numbering and how outline numbering interacts with styles is crucial to your success in using Word with legal documents. Basic outline numbering can be handled much the same way as bullets and numbering. Seven default outline numbered lists come with Word. Three of the lists format the paragraphs with outline numbers. These lists are in the top row of the dialog box. The remaining four format the paragraphs with outline numbers and apply heading styles to the paragraphs and can be found in the bottom row.

Partly because of an expected shortage in certain ISBN categories, the International Organization for Standardization (ISO) decided to migrate to a thirteen-digit ISBN (ISBN-13). The process began 1 January 2005 and was planned to conclude 1 January 2007.[48] As of 2011, all the 13-digit ISBNs began with 978. As the 978 ISBN supply is exhausted, the 979 prefix was introduced. Part of the 979 prefix is reserved for use with the Musicland code for musical scores with an ISMN. The 10-digit ISMN codes differed visually as they began with an "M" letter; the bar code represents the "M" as a zero (0), and for checksum purposes it counted as a 3. All ISMNs are now 13 digits commencing 979-0; 979-1 to 979-9 will be used by ISBN.
This is how our document looks. It’s 16 pages long and has page numbers applied to it, as in Step 1, throughout. You can see that the main text of the book starts on Page 7 of the document, and that the page number marker has adjusted accordingly to mark this as 7. But we want this to be numbered as 1 in the book instead. So, let’s discover how to do just that.
Some drawbacks to this feature are that you lose a little control when you are typing. Word formats for you and some users do not like this. Also, on certain items, you will get a number when you do not expect or need one. For example, you have an attorney whose name begins with an initial (A. George Smith). When you type the name and press ENTER, the first initial "A." converts to an automatic number.
In the Bullet or Number Position section, set the Alignment to Right. The Left Indent is where the text will start. The First Line Indent is the amount of space that should be subtracted from the left indent to determine where the period after the number will be positioned. This was determined in the first step with the spacing placeholder text. Leave Tab Position blank and check Preview to see the options take effect in the highlighted text. Make any needed adjustments to the positions, and when you are satisfied, click OK.
Formatted number used for sound recordings, printed music, other music-related materials, and video recordings. Publisher's and distributor's numbers that are given in an unformatted form are recorded in field 500. A print constant identifying the kind of publisher or distributor number may be generated based on the value in the first indicator position. Repeatable for multiple numbers associated with an item.

In Australia and New Zealand, the current standard (Australia/New Zealand joint standard AS/NZS 4819:2011 - Rural & Urban Addressing)[6] is directed at local governments that have the primary responsibility for addressing and road naming. The standard calls for lots and buildings on newly created streets to be assigned odd numbers (on the left) and even numbers (on the right) when facing in the direction of increasing numbers (the European system) reflecting already common practice. It first came into force in 2003 under AS/NZS 4819:2003 - Geographic Information – Rural & Urban Addressing.[7] Exceptions are where the road forms part of the boundary between different council areas or cities. For example, Underwood Road in Rochedale South, divided between Logan City and the City of Brisbane.

All of this happens in the Bullets & Numbering dialog box, shown below. You will definitely want to use paragraph styles for this. My first one is called Chapter title. You will need to begin by changing the List Type to Numbers for all of the levels, and you must both name the List and use the same named list for all Levels. You do this by selecting the List > New List.
For some documents, though, you’ll want to get a little fancier. For example, what if you don’t want the page number to appear on the first page of the document (or on the first page of each section)? Or what if you want the page number placement to be different on odd and even pages, the way it is in a book? Or what if you have different sections that you want to be numbered differently—like an introduction or table of contents where you want Roman numerals instead of the Arabic numerals used in the rest of your document?

Law firms use numbered lists daily to prepare contracts, pleadings, letters and memos. Word makes activating and customizing numbering fairly straightforward. You can create simple numbered lists, such as A, B, C and 1, 2, 3. You can also customize these lists to setup specific numbering styles for your firm and practice group. Multilevel lists such as I, A, 1 are handled through Word's Outline Numbering feature, which is explained later in this chapter. Many firms rely on outline numbered lists to draw up contracts and pleadings. Like numbered lists, outline numbered lists can be customized.
