What are DOIs and URLs application and usefulness in the medical publishing world?

When looking / searching online for a reference the DOI or URL is the reference that will help identify correctly and accurately the reference that is being researched. All modern major and important scholarship involving references end with either a DOI or a URL.

What is the DOI and its implications?

The DOI is an acronym for Digital Object Identifier. It is a unique alphanumeric code that identifies content and provides a permanent and unerasable link to its location on the internet. DOIs can be found in database records and the reference lists of published works. These cannot be erased or altered. Even if the website changes the DOI does not and can be found by clicking on the DOI link. The DOI never changes thus making it a stable link, unlike a URL. Each DOI points only to just one specific item. This can be in the form of an article, book chapter or dataset. The DOI starts with '10' and is a series of numbers and letters (alphanumeric) for example 10.1002/anie.202301011.

Once the DOI is entered into a DOI resolver (example: doi.org) it will lead the viewer / researcher directly to the article that has the DOI typed in.

It is typically located on the first page, near the details of the paper that has been published. The DOI assists readers quickly find the original source and also serves as verification for the authenticity and citable nature of the work. The DOI is now found to be essential for modern academic citation in styles like APA, MLA, and Chicago.

In short, a DOI ensures research is findable and citable, no matter where it moves online

What is the URL and its implications?

URL( Uniform Resource Locator) in a scientific paper provides direct access to online sources. However, it requires specific formatting based on citation style (APA, MLA, etc.). This usually involves the name of the author, date, title, website name, and the URL itself, often with an access date and sometimes in plain text or as hyperlinks. These however can change.

When to insert DOIs and URL in publishing an article or when searching for a paper

Follow these guidelines for including DOIs and URLs in references:

  • Include a DOI for all works that have a DOI, regardless of whether the online version or the print version has been used.
  • If an online ( print or e published) work has both a DOI and a URL in it then only include only the DOI.
  • If an online work has a URL but does not have a DOI, then only include the URL in the reference.
  • For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
