What is a DOI?
A Digital Object Identifier (DOI) is a unique alphanumeric string assigned to scholarly publications, including journal articles, conference proceedings, and ebooks. It provides a permanent link to the source, making it easy for readers to access the original work. Using a DOI ensures that your references are precise and verifiable, which is essential for academic credibility.
For example, the DOI 10.1038/s41586-020-2649-2
directly links to a specific scientific article, ensuring that anyone accessing your reference can find the exact source.
