What a DOI Is
A Digital Object Identifier is a permanent name for a published work. It is not a location. It is a string that a resolver service translates into wherever the work currently lives.
Most scholarly DOIs are registered through Crossref, a membership organisation of publishers that also distributes the metadata attached to each identifier.
The Problem It Solves
A plain web address records where a file happened to sit on the day you copied it. When a journal redesigns its site, changes host or reorganises its archive, every citation pointing at that address breaks. This is link rot, and in scholarly literature it is pervasive.
A DOI records what the article is rather than where it lives. The publisher keeps the pointer current, so a citation written today still resolves years later even after the site is rebuilt.
Anatomy of a DOI
| Part | Example | Meaning |
|---|---|---|
| Resolver | https://doi.org/ | Redirects the identifier to the current location |
| Prefix | 10.56975 | Identifies the registering publisher; always begins "10." |
| Suffix | ijcrt.v14i9.400073 | Identifies the individual work within that publisher |
Anything that does not begin with "10." after the resolver is not a DOI. The suffix carries no meaning you can rely on — publishers structure it however they like.
The Metadata Behind It
Registering a DOI deposits a structured record: title, authors in order with affiliations, abstract, journal title and ISSN, volume, issue, pages, publication date, licence, the article URL and the reference list.
That record is what flows to indexing services, reference managers and author profiles. It is why a complete, correct deposit matters far more than it appears: an error in an author's name propagates everywhere, and correcting it afterwards requires a formal update.
Citing a DOI Correctly
- Give the DOI as a full link:
https://doi.org/10.56975/ijcrt.v14i9.400073 - Do not write "DOI:" before a full URL form — choose one style and apply it consistently
- Include the DOI in every reference where one exists
- When sharing your own work, share the DOI link rather than a PDF, so views and citations attach to the record
Anatomy of an IJCRT DOI
Resolver → prefix 10.56975 (IJCRT’s Crossref prefix) → suffix: journal, volume 14, issue 9, article identifier. A real example: doi.org/10.56975/ijcrt.v14i9.400073
Check any IJCRT DOI yourself in Crossref Search or the Crossref journal record.
Finding a DOI
- Check the article's first page or its landing page on the publisher's site.
- Search the title in Crossref's public search.
- Use your reference manager's lookup, which queries the same metadata.
- Check the publisher's citation export, which usually includes it.
Not every work has a DOI. Older articles, some conference papers, theses and reports may have none; cite them by their other details rather than inventing an identifier.
When a DOI Does Not Resolve
- Check for a copy-paste error, especially a truncated suffix or a trailing full stop captured from a sentence.
- Allow time if the article is very new — a newly deposited DOI takes a short while to activate.
- Try the identifier directly at the resolver rather than through a third-party link.
- Search the title to confirm the article exists and check the DOI printed on it.
- If it still fails, contact the publisher — a broken DOI is their responsibility to repair.
Common Misconceptions
| Belief | Reality |
|---|---|
| A DOI means the journal is indexed | No. It means an identifier is registered. See journal indexing explained. |
| A DOI proves quality | No. It proves the article exists as published and resolves. |
| A DOI can be deleted | It is intended to be permanent. Retracted articles keep their DOI and gain a notice. |
| Every article has one | Many older and informally published works do not. |

Quick Checklist
- Full link formGive the DOI as https://doi.org/10.xxxxx/suffix
- Copy, never retypeOne wrong character breaks the link
- Test itOpen the link before you put it in a CV or thesis
- Share the DOINot a PDF copy, so views and citations attach to the record
DOIs in Short Form and as Links
| Form | Example |
|---|---|
| Bare DOI | 10.56975/xxxxx |
| Link (recommended) | https://doi.org/10.56975/xxxxx |
| Old forms | doi:10.56975/xxxxx or dx.doi.org links |

Frequently Asked Questions
Is a DOI free at IJCRT?
A Crossref DOI is optional and registered on request after acceptance, for ₹300 (Indian authors) or $20 (foreign authors). IJCRT’s DOI prefix is 10.56975.
Does a DOI mean my paper is indexed?
No. A DOI is a permanent identifier for one article; indexing is coverage by a search or abstracting service. They are separate.
How do I find the DOI of a paper?
Look on the article page or PDF, or search the title in Crossref Search. If a paper has a DOI, it will appear there with its metadata.
Which DOI form should I use in references?
The full https://doi.org/ link.
Can DOIs change?
No. A DOI is permanent, though the URL it points to can be updated.
