What is DOI (Data Object Identifier)?
Answer
The DOI (Data Object Identifier) is used for electronic sources, such as a journal in a subscription database, to provide location information in citations. The DOI is a series of numbers representing the unique identifier of the content (database name) and link to the content (the URL). If no DOI is provided by the database, then the standard retrieval statement must be used in the citation entry.
The DOI is a unique alpha-numeric code that is assigned to articles and books by their publishers when an electronic version is available. When you have a DOI, you don't need to state a URL or database name.
