Keeping up a contents page
It is a useful idea to keep a rough contents page as you go along. You project may grow to as much as 100 pages by the time you have done, and being organised will make it easier.
In fact it is essential that the pages are numbered. This is easy if it were all one Word document, but it won't be, so number each page by hand. Use section numbers, such as A1, b3, e7, as this is easier if you add extra pages.
Every time you add a page add it to your Contents.
That way it will be easier when you get to the end!
