A Digital Object Identifier (DOI) is a persistent and stable identifier for electronic materials. The advantage of using a DOI in the online environment is that it can be expressed in resolvable format, (e.g. https://doi.org/10.32613/nrp/2021.4) so that there is always a link back to the online location of the item.
An International Standard Book Number (ISBN) identifies a book by format (print, audio etc.), edition and publisher. They simplify book distribution, and purchase, and improve the chances that a book will be found and sold.
It is not necessary for an ISBN and DOI to be issued for the same publication unless it will be distributed in both print and electronic formats.
The Library can provide you with these identifiers if you meet certain conditions. Please see the guidelines below and request the appropriate identifier using the related form.
Note: A research report does not require an ISBN to meet the government guidelines or be eligible for National or State Legal Deposit.
