Digital Object Identifiers (DOIs) are persistent and unique identifiers for digital objects such as scholarly articles, datasets, and other research outputs. This means that even if the location or metadata of the object changes, the DOI remains constant, ensuring reliable access to the content over time.

The Scholarly Communication Department can mint DOIs for all scholarly work deposited in our institutional repositories: DataCORE and IUScholarWorks.  This service is free of charge and available to all IU faculty, staff, and students.

Digital Objects

DOIs can be minted for most digital research outputs. Examples of digital research outputs are:

  • Journal articles
  • Preprints
  • Datasets
  • Theses and dissertations
  • Supplemental material and addendum
  • Scholarly presentations


Why mint a DOI?

DOIs provide multiple advantages:

  • Persistent Identification: DOIs are a persistent and unique identifier for digital objects. This ensures reliable access to the content over time.
  • Citation and Attribution: DOIs facilitate accurate citation and attribution of digital content. This ensures proper credit is given to the creators.
  • Sharing: DOIs ensure that others are able to locate material with ease.
