Within the 979 prefix element, the registration group identifier 0 is reserved for compatibility with International Standard Music Numbers (ISMNs), but such material is not actually assigned an ISBN.[12] The registration group identifiers within prefix element 979 that have been assigned are 10 for France, 11 for the Republic of Korea, and 12 for Italy.[37]
Thanks very much for your prompt reply, which reassured me that I was on the right path. From having read various Help topics, I suspected that I'd have to use an Excel data source for the numbers. Fortunately, my knowledge of Excel was good enough to know about the drag and drop facility to create automatic sequential numbering, so the data source creation was easy. In the end, it was the mail merge (no surprises?) which proved a tad tricky, but I got there in the end. I've used MM many times and quite happily in Word documents, but for Publisher label format, it was of course a bit different. The important bit that I had to discover for myself was the significance of, after getting to the Print stage, going into Print options, to Publication & Paper Settings, and selecting Multiple Pages per Sheet (& in my case, also "Single-sided" cos my default of duplex printing had come up). But TA-DA!  All is fine now. Thanks very much again.
Now, select the relevant page icon in the Pages Panel which represents the page you want to set as the first page of the second section of your document. In this example, this is Page 7 (which is currently numbered as vii). As before, go to the drop-down menu in the Pages Panel and select Numbering & Section Options… to open the Numbering & Section Options window. Again, check Start Page Numbering at, and from the Style drop-down menu select 1, 2, 3, 4… from the options available. Click OK.
If you want numbered headings to be underlined, but do not want a line under the number, it can be difficult if you don't know how it works. This is because by default, the format of the number follows the format of the text that follows it. For example, let's say you want to underline a paragraph in a Heading 2 style. Chances are it will look like this:
The first conscription numbering was ordered by Maria Theresa in 1770 and implemented in 1770–1771. The series was given successively as the soldiers went through the settlement describing houses with numbers. Thereafter, every new house was allocated the next number sequentially, irrespective of its location. Most villages still use their original number series from 1770–1771. In cities, houses have been renumbered once or more often in order to be sequential – the first wave of renumbering came in 1805–1815. In 1857, the Austrian Emperor allowed a new system of numbering by streets. This new system was introduced in the biggest cities (Prague, Brno) in the 1860s. In 1884, land registration books were introduced and they used the old (conscription) numbers as a permanent and stable identifier of buildings. The new (orientation) numbers continue to be used concurrently.

You have two choices when faced with the task of numbering headings in a Word document. You can enter the numbers manually and hope nothing changes — lots of luck with that one. Or you can opt for the more efficient solution and create and apply a numbered style. Unfortunately, that can get you into even more trouble, if you don't know what you're doing. To avoid surprises, follow these 10 steps to add a numbering scheme to a style.
InDesign is a popular publishing software application released by Adobe. It is often used by graphic designers to publish books, magazines and brochures. Along with important elements like text, graphics and logos, page numbers are essential to these publications. It is possible to add the page numbers during or after the document's completion, if you know where to look. This article will tell you how to add page numbers in InDesign.
multilevel headings in legal format are just soo badly broken. If it requires 6 steps to do a basic everyday document management process, why is there not a choice for a more reliable solution. I have been fighting this for about half  an hour – I may was well use notepad to do my documentation at this point, but I will persevere… or I will start a brand new document. How broken a solution is that. …car won't start, get a new car!  Thanks for the pointers, almost there.
On some long urban roads (e.g. Parramatta Road in Sydney) numbers ascend until the road crosses a council or suburb boundary, then start again at 1 or 2, where a street sign gives the name of the relevant area — these streets have repeating numbers. In semi-rural and rural areas, where houses and farms are widely spaced, a numbering system based on tens of metres or (less commonly) metres has been devised. Thus a farm 2,300 metres (7,500 ft) from the start of the road, on the right-hand side would be numbered 230.[8]

Another scheme is based on residential areas called cư xá. A cư xá is addressed by house number, road, and cư xá, for example "123 đường số 4 cư xá Bình Thới". Some localities still use an older address format based on neighborhood (khu): for example, in "7A/34 Tô Hiến Thành", 7A is the neighborhood number. This confusing format is being gradually phased out in favor of the more modern formats above.

If you need to apply numbering within a paragraph rather than to the entire paragraph, you use Word's ListNum feature. Using the ListNum feature will allow you to take advantage of the numbering system you're currently using in your document (it will use the one you implemented most recently if you're not currently using a numbering system). The ListNum Field is available in Word 97 and later and interacts with multi-level list numbering (which should be linked to styles as set forth here). Here is a brief explanation of differences between the ListNum field and the Seq field.
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. numbering using word
