When citing electronic sources consulted online, the Chicago style citation manual recommends including an electronic resource identifier, where possible, to lead your reader directly to the source.

A URL is a uniform resource locator, which directs the reader straight to the online source. When using a URL, simply copy the address from your browser’s address bar when viewing the article. You must include the source’s full publication information as well.

A DOI is a digital object identifier; a unique and permanent name assigned to a piece of intellectual property, such as a journal article, in any medium in which it is published. If it is available, a DOI is preferable to an ISBN.
