Method comparison

In the following diagrams each pair of pages is printed on a single leaf, with the odd-numbered page on the front and the following even-numbered page on the back. Text lines added during the update are shown in red, while leaves needing to be updated are highlighted in yellow.

It is useful to compare how the two methods handle the addition of new material. For example, assume you are adding a paragraph of text to the following pages:

Full looseleaf

If you are using the full looseleaf method, a new leaf will be created for the overflow from page 6 caused by the additional text. In order to make it fit in the numbering scheme, the point pages 6.1 and 6.2 are generated. The remaining leaves (7–8 and 9–10) are not altered and do not form part of the update. This results in a smaller (4 page) update, but a larger (12 page) total document size.

Change pages

Using the change pages method, the new text causes the following material to re-flow until a suitable gap (for example, a section end) is encountered. This results in a larger update pack (6 page) than with the full looseleaf model, but the overall document size remains at 10 pages and the required filing is easier to perform.
