# Understanding the CCCURJ identifier

Every paper has a permanent identifier of the form **CCCURJ:YYMM.NNNNN**, for example **CCCURJ:2610.00014**.

- **YYMM** is the two-digit year and month in which the paper was first submitted.
- **NNNNN** is a five-digit sequence number within that month, starting at 00000.
- A specific version is written with **v** and the version number, for example **CCCURJ:2610.00014v1**.

## How to cite a paper

Cite the identifier with the primary category, for example **CCCURJ:2610.00014 [q-bio.GN]**. Cite a specific version when the details matter. Each abstract page shows both forms under *Cite as* and gives a BibTeX entry.

If the paper has been published, cite the published version as well. Its journal reference and DOI are shown on the abstract page.
