Looseleaf terminology

The content of a looseleaf document is rendered to a set of leaves. Each leaf is normally printed on both sides, with the odd numbered page on the front and the even numbered page on the back (for example, page 65 and page 66 define the printed leaf 65). Intentionally blank pages are included where necessary to retain the leaf structure.

Each looseleaf publication begins with an initial release. At some predetermined time, an update release is created. The update release takes the form of an update pack consisting of a set of updated leaves, together with a set of filing instructions that explain when pages are to be removed or replaced, and where new pages should be inserted. There may also be a live pages list, which shows the release in which each page was last revised.

A full release can be generated whenever there is a need to produce a copy of the entire looseleaf publication.
