Now you need to check the position of the page breaks and adjust them where necessary. Type page breaks in the search window and press return. Use Format, Paragraph to space text vertically on the page. Never add extra, empty paragraphs to alter the vertical spacing of the text. Subsequent additions or deletions to the text mean that such paragraphs could cause blank space in your documents.
Footnotes are difficult to place well.
Those that occur close to the bottom of a page often flow onto the next page because there is not enough free space on the present one. This part of Word is not as robust as the basic functions. Sometimes the footnotes wander even when their reference mark is in the top half of a page. The only remedy is to adjust the text by re-phrasing it more concisely, or more fulsomely, or adjusting the spacing between nearby paragraphs. Inserting a manual page break should be a last resort.
