A digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet.
Our publishing system assigns a DOI automatically when an article is published and made available electronically. We recommend to include them for both print and electronic sources.
For example DOI https://doi.org/10.4101/jvwr.v8i2.7186
will lead to JVWR web site volume 8 issue 2 paper 7186.
Where is the DOI?
The DOI is located on the first page of the article, under the link to the full article.

How do I use it
In your papers, add the URL of the DOI near the top of your paper.

Both will allow users to find the article faster.
