Updating your URLs

If you have created DOIs, you will at some point need to update the URLs registered for those DOIs.  To update your URLs, you can either

• re-deposit your metadata with the new URLs included - or - 
• send us a tab-separated list of DOIs and their new URLs, and we'll process the update for you.

If you are providing a tab-separate list, we can usually process your request within 24 hours. If you need your URLs updated on a specific day or have a large number of URLs to update (over 100,000), you should to coordinate the update schedule with Support to avoid delays. We can provide a list of your existing DOIs and URLs if needed.
