# What does "no comparison" mean in a blockspace.news edition?

The books were rewound between two snapshots, so the edition prints no difference rather than a negative.

It means block.space's books were rewound between two daily snapshots, by a re-sync or a [reorg](https://blockspace.wiki/glossary/reorg/), so the two cannot be compared. The [edition](https://blockspace.wiki/glossary/edition/) says "no comparison" instead of printing a difference, and never shows a negative. Separately, a figure missing from a snapshot reads "[not measured](https://blockspace.wiki/glossary/not-measured/)", never zero, and is left out of any share.
