What is a DOI?
A DOI (Digital Object Identifier) is a unique alphanumeric code assigned to a digital publication, such as a journal article, ebook, or research report. It provides a permanent and reliable link to the online source.
Why DOIs Matter
- Permanent Link: Unlike URLs, DOIs never change, ensuring long-term access.
- Credibility: Used by academic databases and journals for authentic citation.
- Efficiency: Helps readers find digital sources quickly and accurately.
How DOIs Work
Each DOI is registered through an international agency and linked to a specific document. It resolves to the current location of that document when entered in a DOI resolver, such as https://doi.org.
DOI Format Example
Example: 10.1000/xyz123
You can access it by typing: https://doi.org/10.1000/xyz123
Where to Find DOIs
- On the first page of journal articles.
- In database listings (e.g., PubMed, JSTOR).
- In the citation information provided by publishers.
Using DOIs in Citations
APA Example: Smith, J. (2023). Climate policy in urban planning. Journal of Environmental Research, 15(2). https://doi.org/10.1000/xyz123
Final Thoughts
DOIs make academic references more reliable and accessible. Always include them when available: they guarantee that your readers can locate your cited sources accurately and efficiently.
