Persistent Identifiers

The UW Libraries provides tools to help create persistent identifiers or persistent archived versions of web pages. UW has institutional accounts for both of these services.


  • perma.cc creates a permanent snapshot of a webpage or web resource that you'd like to reference in a publication, such as an article, dissertation, or another web resource. This "snapshot" will create an archived version of the referenced page as of a specific date in time, and will give it a persistent address. For more information on perma.cc, see our guide.
  • DataCite assigns a Digital Object Identifier (DOI) to create a permanent address for a website, such as a project website, curriculum materials, etc. The back-end location of the resource can be changed, but the public-facing URL for the item(s) will remain the same. For more information on DOIs, see our guide.
