Say you have a 5 pages document that you need to insert footnote or endnote in it.
Endnote will place a note at page number 5.
Footnote will place a note at the same page you write the note in.

In order to insert footnote and endnote:

1. Open word 2007.
2. Go to "references".
3. Click "Insert Footnote" or "Insert Endnote" as you wish.

When cutting text and pasting on a different page, the footnotes goes with the marked text
along with the numbers, so basically if having 3 notes on page and cutting note number 3 and
pasting on another page, the pasted note will get the numeric value of its place in the
text automatically.
