In recent years research has been gaining immense popularity to find the facts and novel approaches for sustainable development. Along with the digitization of the research industry, DOI (digital object identifier) is also becoming the buzzword.

To cope with the exponentially growing research industry, it's required to document all the findings as research articles for future reference.

So, recorded scholarly articles need to be published via some digital way called open-access journals. As general terminology, or to start with, DOI can be understood as a tool that helps the research community quickly find these scholarly articles from the ocean of WWW.

So, What is DOI? 

It is a non-repetitive and constant group of characters, numbers, symbols, special characters and words linked with online journals, articles, books and many more intellectual digital works for a perpetual period.

It works as a permanent web address just as a URL for research papers/articles/books, like any other website URL. By clicking on it, an authorized person can access the e-resources online quickly, without thinking about other complexity.

DOI Examples

  • doi:10.1080/8585748585.2022.1770549

Types of Digital Objects Can Have DOI

  • Academic journal articles
  • Research reports
  • Governmental reports
  • Data sets
  • Books
  • Conference proceedings
  • Code
  • Media

Importance of DOI

DOI is used for permanently citing the documents in www. You may say research articles can be accessed via the publisher-provided URLs, but what happens if the publisher’s website may lose its domain or may find some technical problems in hosting?

When the digital document cannot be accessed via the URL provided by the publisher, in such a scenario, DOI is the only solution for accessing the document. DOIs make it easier to retrieve your digital document.

We can say that DOI is more stable than standard web links. Attaching DOI with the research documents or any other digital object will boost your citation count.

To summarize, it would be good to write here: “DOI resolves the problem of finding digital objects online at the fingertips”.


To get DOI, you must register with the agencies affiliated with International DOI Foundation. One such leading agency is crossref. Approved agencies are responsible for maintaining the database of DOI. Many times, DOI is also termed as Crossref DOI due to the popularity of crossref. Crossref offered two types of the account by which you can have DOI: 

  • Direct Account - Apply as an independent member 
  • Indirect Account - Under the Sponsored Member

DOI is a permanent weblink of a digital object used to easily locate the concerned object on WWW.

DOI is used to cite the research papers in the reference part. It provide the pin point reference for the readers and reviewers.

No, DOI is not compulsory, but it is good to have a thing.

DOI helps in finding the research paper very easily on the internet.

URL is bound to the domain system and hosting server, whereas DOI is the facility from independent servers infrastructure. Therefore, the URL may not work in case of failure in the hosting environment or the publisher does not renew DNS. DOI is immune from the problems which URL faces.
