# Extraction citation mode control (line, word, block)

> Set citationMode to line, word, or block so extraction citation polygons match the granularity you need; parse 2.0.0-beta now supports bounding box citations.

When bounding box citations are enabled on an extractor, you can set **`citationMode`** in **`advancedOptions`** to **`line`**, **`word`**, or **`block`** so citation polygons match the granularity you want. If you leave it unset, behavior matches what you have today (line-based citation processing plus block overlap handling across supported parse engines).

Extraction pipelines that use the **parse 2.0.0-beta** engine can now return bounding box citations for extracted values, so you are not limited to older parse versions when you need spatial references.

See [Citations](/extraction/response-format#citations) for how citations appear on extracted fields.

* **`citationMode`** — optional; configure in extractor advanced options in Extend Studio or on extractors (`line`, `word`, or `block`)
