Once the DOIs have been successfully submitted to Crossref, it should resolve. This means: clicking on the hyperlinked DOI or searching for the DOI will take you to the exact article for that DOI. In other words, the DOI will turn into the URL where the article is to be found. There may be a delay if there is a large queue of requests to set up new DOIs before the DOI correctly resolves.

Resolve DOIs using the following:
