# Number of pages (`number_of_pages`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Number of pages of a book, journal issue, report or document, as a non-negative integer. Library catalogues also write the extent as text, such as xii, 345 p., which is not this type. Any integer looks the same, so there is no regexp; detect the type by field names such as pages, page_count, num_pages and number_of_pages.
