Explanation:
There are two main reasons to include the DOI (Digital Object Identifier) over the URL (Uniform Resource Locator) in a reference list when both are available:
Reliability: DOIs are persistent identifiers. This means they permanently link to a specific piece of content, even if the URL changes over time. Websites can move locations or restructure their content, making old URLs unreliable for finding the same information later. A DOI, on the other hand, will always lead you to the correct source,regardless of any website changes.
Accuracy: DOIs are assigned by a registration agency and guarantee you're referencing the intended work. URLs can be misleading and might lead to a different version of the content, a different work altogether, or even a broken link.
