A

DOI (Digital Object Identifier) is a unique, persistent identifying number for a document published online. It appears on a document or in a bibliographic citation as an alphanumeric string of characters that acts as an active link to the original digital object (journal article, report, etc.).

DOI was introduced in 2000 by International DOI Foundation. It is part of a larger registration system, called Handle System, for information resources.

DOI is a string in the format of prefix/suffix, where "prefix" identifies who is a publisher, and "suffix" identifies a specific document published by the publisher.

The "prefix" is expressed in the format of 10.publisher, where "10" is the DOI namespace given by the Handle System. and "publisher" is the DOI registration number given to the publisher. For example, 10.1109 identifies IEEE as the publisher.

"suffix" can be any string used by the publisher to uniquely identify the document. For example, 5.771073 identifies the article "Toward unique identifiers" published in "Proceedings of the IEEE - Volume: 87 Issue: 7".

Examples of DOI:

10.1109/5.771073
10.1111/hex.12487
10.1016/j.jpsychires.2017.11.014
