What is a DOI?
A Digital Object Identifier (DOI) is a unique alphanumeric string assigned to a digital object. A DOI links persistently to a publication so that any link or reference to it should take a user to where the article currently resides online. They are useful for citation metrics, facilitate access to content and is also a way to overcome the problem of dead links.

DOI minting for papers, data and higher degree theses
The Library provides DOI minting service for papers, data and higher degree theses for NTU staff and students. In order for the Library to mint a DOI, the item must fulfill these essential criteria:
To apply a DOI for your paper, please contact us, you need to provide the minimum required metadata information for the item as listed below. The metadata information submitted will be open to the public and used freely for discovery.
If your data is hosted in DR-NTU (Data), a DOI will be assigned to it automatically. If you need to know more about data DOI minting, please contact the Library’s Research Data Management team.
All the higher degree theses (Ph.D. and masters by research only) submitted to DR-NTU have been automatically assigned DOIs. The embargo status of theses does not change with the DOI minting.
To find the DOI of your thesis, go to DR-NTU to do a title or name search or you can also search via Google. Click on the title of your thesis, and the DOI will be listed in the record. Please include the DOI when citing your own thesis. If you have any questions, please contact us.
