Dear Sean,

Page renumbering is a process that is easier to do than to describe, in no small part because trial and error come into play more often than not. Such being the case, you might be able to figure out how to number the file folios as you wish once you are led to the necessary tools. So that's what I shall try to do here.

First of all, my guess is that your version of Word is of more recent vintage than mine (Word 2003). Still, the menu items have probably changed little, if at all, and certainly not unrecognizably.

1) If your docuмent is already paginated, double-click in either the header or the footer—depending, that is, on where your folio is placed (for simplicity's sake, let's assume that it's in the footer; the instructions that follow apply in either case). If it isn't paginated, click the View dropdown and then click Header and Footer.

2) When the footer appears, a context menu ought to appear with it. In that menu, click on the Format Page Number tile. You should be able to figure out the options pretty readily. If you can't renumber to your satisfaction with this tool, move on to …

3) With the cursor still in the footer, click the File dropdown in the main menu and then click Page Setup. Choose the Layout tab, and familiarize yourself with the options offered there. As I said at the outset, trial and error are to be expected.

If all fails, you can send me the file with a description of what you want done, and I'll see if I can format it to your liking.

Does anyone know how to begin page numbering later in a docuмent (Starting with 1 on the 6th page)?

In the now nominally obsolete version of Word ^[*] that's the most recent I've used, perhaps the most important top-level menu for your inquiry is--surprise!--the Insert menu.

If I understand your question, and if your modern Word 2016 ^[♀] handles your request enough like my nominally obsolete version that you can find a way to do the same, then it's important for you to realize that by default, your entire docuмent is considered by Word to be a single section.  I believe that you want to put a section-break between your pages 5 and 6.

Then you might be able to click at the beginning of that newly separated 2nd section, then select Insert → Page Numbers → Format.  This should present a Page Numbering box; look for a Start At input-slot, and scroll to or type 6, then OK.

For your neglected 1st section, you might be able to use Insert → Page Numbers → Format to display its numbers as "i, ii, iii, iv, v",  or something else that meets your needs.

Alas, MS loves to change interfaces for no compelling reason; I offer no guarantee that they've even retained the 20th-Century concept of a section.  So you might need to rummage around a lot.  Be that as it may, you might find that section is a crucial word for productive ad hoc searches on the Internet.

Note *: Word 2000, which by that date already had more features than those for which I've ever found a need, and it handles my more-than-a-hundred pages and more-than-a-thousand footnotes well without blowing up.  The only desirable capability it doesn't have is text that flows thro' multicolumn pages (i.e. any more than 1 column) without Word tables (altho' its manual--preprinted (gasp!)--seems to indicate that I'm wrong about that drawback, but decades have now passed).

Note ♀:  Ah, yes, 2016: The Bill-&-Melinda-Gates version of Word honoring their eager anticipation of "Madame President".

If it's the new version it's in with the header opinions
