E-books and electronic journal articles can contain a number which identifies them, called a DOI (Digital Object Identifier). A DOI is a string of numbers, letters and symbols used to permanently identify an article or document and link to it on the web. A DOI will help your reader easily locate a document from your citation. It is like a PPS number for the article you’re citing — it will always refer to that article, and only that one (source: UIC).
A DOI is not the same as an ISBN, but it does the same thing - it is a unique number assigned to a piece of work that allows you to find the work even if the work moves databases or websites, etc. The DOI is a hyperlink which can take you to the article in one click.
If you know the DOI it is best to include it in your references/bibliography so that you know you're linking directly to the correct article, and to make it easy for the reader to check the source.
