# Publication

A PageSeeder concept that was redefined with the release of version 5.96xx.

With this version, PageSeeder introduced the [publication ID](publication_id.md) and the [publication config](publication_config.md). The implementation of these two concepts made collection-level processing easier and more powerful.

As a server-wide, unique identifier, the publication ID makes it straightforward to find the root document in collections that use [xrefs](cross_reference.md) to embed or transclude content into a single hierarchy. While the publication ID is typically attached to a [references document type](references_document.md), any document can be a publication.

With the publication config, the same document can simultaneously exist in multiple publications while being numbered according to different schemes, positions in the publication hierarchy or collection-level versioning. *See* [publications and publication types](../../guide/configuration/publication_types.md).
