How to Find a DOI for a Research Paper
Finding a DOI for Academic Papers
To find a DOI for a paper, start by checking the first page of the PDF or the journal's landing page. If it is not visible, use the Crossref Metadata Search tool or search the title in Google Scholar. Most DOIs begin with the number 10 and contain a prefix and suffix separated by a slash.
Step 1: Inspect the Document Header and Footer
Start your search by looking at the source document itself. Open the PDF of the research paper and examine the first page. Most academic publishers print the DOI in the header, the footer, or the sidebar alongside the publication date and volume number. Look for a string of text that begins with 'doi:' or 'https://doi.org/'. If you are viewing the article on a database like JSTOR or Elsevier, the DOI is typically listed in the metadata section near the abstract. Always copy the full string starting from the number 10 to ensure your citation is accurate.
Step 2: Use the Crossref Metadata Search
If the DOI is not printed on the paper, use Crossref, the official registration agency for scholarly DOIs. Navigate to the Crossref Metadata Search website and type the full title of the article into the search bar. You can also add the lead author's last name to narrow down the results. The search results will display the article title, authors, and the assigned DOI directly beneath the entry. This is the most reliable method for finding DOIs for articles published after 2000, as Crossref maintains the central database for most academic publishers.
Step 3: Search via Google Scholar
Google Scholar is a powerful alternative for locating missing DOIs. Enter the article title in quotation marks to find the specific entry. Once the result appears, look for a link that says 'Cite' (represented by a quotation mark icon). While the citation preview may not always show the DOI, clicking on the title link will often take you to the publisher's version of the page, where the DOI is prominently displayed. Additionally, some Google Scholar results include the DOI directly in the snippet text below the title if it has been indexed correctly.
Example: DOI Lookup for a Journal Article
Suppose you need to find the DOI for the following paper: **Title:** 'The Impact of Social Media on Mental Health' **Author:** Jane Smith **Journal:** Journal of Psychology, 2022 1. **Crossref Search:** Enter 'The Impact of Social Media on Mental Health Smith' into Crossref. 2. **Result:** The system returns: `10.1016/j.jpsych.2022.01.005`. 3. **Verification:** Visit `https://doi.org/10.1016/j.jpsych.2022.01.005` to confirm it redirects to the Smith article.
Common Mistakes to Avoid
Avoid these frequent errors when searching for and using DOIs:
- Confusing the DOI with the ISSN: The ISSN identifies the journal, while the DOI identifies the specific article. Always use the string starting with 10.
- Including 'doi:' in the URL: When creating a clickable link, do not write
https://doi.org/doi:10.xxx. The correct format ishttps://doi.org/10.xxx. - Using a Database URL: Do not mistake a library proxy URL (e.g.,
ezproxy.library.edu) for a DOI. These links only work for students at your specific university. - Assuming all papers have DOIs: If a paper was published before the mid-1990s, it may not have a DOI. Do not invent one or use a placeholder.
