# Can I update my article after assigning a DOI?

### DOI versioning

At Authorea we believe that research communication should be dynamic, allowing researchers to respond to feedback and reviews. Consequently, we believe that once a work is shared publicly and assigned a DOI it should have the ability to be updated. At Authorea you can take advantage of **versioned DOIs**. 

Even if your research document already has a DOI, you can make changes and publish it again. Your DOI will receive a new version, e.g. [https://doi.org/10.22541/au.158817808.80002805/v2](https://doi.org/10.22541/au.158817808.80002805/v2) is the Version 2 of this document. Note the `/v2`.

Each DOI points to a "frozen in time" versioned link, so that we accurately preserve the scholarly record, while at the same time allow updating and correcting the manuscript.
