# label.from.part

Renumber components in each part?

## Description

If `label.from.part` is non-zero, then numbering of components — `preface`, `chapter`, `appendix`, and `reference` (when `reference` occurs at the component level) — is re-started within each `part`.

If `label.from.part` is zero (the default), numbering of components is not re-started within each `part`; instead, components are numbered sequentially throughout each `book`, regardless of whether or not they occur within `part` instances.
