# Book C

URL: https://blockspace.wiki/glossary/book-c/

The content book: the artifact bytes alone, the body of the file or message with all framing removed. In the [partition](https://blockspace.wiki/glossary/the-partition/) it is content only, "the artifact itself".

A protocol that carries no artifact body measures zero in the content book, and that measured zero is not a missing measurement.
