When the “Current Page Number” placeholder sits on a master page, every page to which you assigned that specific master page will display this variable – the number will change automatically on every page. If you change the style assigned to the placeholder on the master page (let’s say you set it to bold), all page numbers will update to that style (all numbers will become bold).

Actually the Numbering & Section Options are not available in the Master page setup which is where the page numbering was set (so that I can have the chapter number appear on all odd-numbered pages). The Numbering & Section Options are, however, available on the normal pages. So that’s where I’ve set the automatic numbering, but of course nothing changes — the book is chapter 1 throughout. As for the setting in the “book panel”, this is something I can’t find. I don’t appear to have a “book panel”. I do have pages panel that seems to fit the description, but there is no add-document setting.
If you go into Print Preview, the field will automatically update in the Headers or Footers. Unfortunately, if you also have the field in the main document, (for example, in the coversheet), going into Print Preview won't update it – but printing will, provided that you have Update Fields ticked under Tools + Options + Print. You can also update the field by selecting it and pressing F9. Or you can press Ctrl+A followed by F9 to update all the fields in the main document in one go.
Warning  Making even minor changes to an outline numbering scheme won't necessarily change the initial position you've selected in the gallery, but rather may create a new gallery position, overwriting an existing one. Because of this problem, attaching numbering to styles is strongly recommended. This is covered in greater detail later in this chapter and in the chapter on Styles.
Do not let me lead you into a headache under false pretences: this FAQ is not going to tell you how to fix a document that contains broken numbering. It simply explains how the numbering works: this is valuable information if you work with Word a lot, and by understanding it, you can often work out how to fix a document. However, this FAQ is not going to tell you how.  (For a discussion of methods, see: List Restart Methods).
To package your book, first select all the documents in your Book file by clicking the first document, pressing Shift, and clicking the last document. Now click the fly-out menu at the top of the Book panel, and choose Package Book for Print. InDesign will take a moment to gather all the info it needs, then you’ll see a Package dialog box (click Package after resolving any warnings), a Printing Instructions dialog box (click Continue), and finally the Package Publication dialog box (see below), where you’ll choose a file name and place to save your packaged folder, and then click Package.

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).

Hello Betsy, I have never heard of any kind of limit on the number of pages in a book. However, once a book gets too big it’s harder to find a good binding to hold it together, and it’s harder to pick the book up. If you’re thinking of anything longer than maybe 3000 pages, you should talk with a printer about proper binding, good thin paper, etc. to make it usable. And consider dividing it all into separate volumes.

Each time you work on a document in your Book file, it’s best to open your Book file first, then double-click the document to open it within the Book file. That way, the Book file remains up to date. If you work on a document outside of the Book file, the Book file will show an error symbol next to that document. If that happens, just double-click the document in the Book file to open it and re-save it to get rid of the error. And after you’ve saved your documents, remember to save your Book file too.
Select documents in your Book file by pressing Ctrl/Cmd and clicking the documents, then click the fly-out menu at the top of the Book panel. If you’ve selected all the documents in your Book file, you’ll see Export Book to PDF in the fly-out menu, and if you’ve only selected some of the documents, you’ll see Export Selected Documents to PDF instead. Click the option you see, and InDesign will present the same Export dialog box you normally get when exporting to PDF in InDesign. Choose your file name and options, click Export, and voila!
If you start to type in what appears to be a numbered list, Word formats your manually typed "numbers" to an automatic numbered list. The main benefit of this option is that you do not need to click any button to start numbering and you can choose your numbering style as well. For example, if you type "(a) some text" and press Enter, it starts numbering using the "(a)" format.
