The Digital Object Identifier (DOI) was opened to the public in October 1997. It provides a regulated means of identifying â€˜objectsâ€™ so they can be accessed and traded even with changes of ownership and location. The article describes the background to the DOI's creation, its current status, and future developments. This article is an expanded and updated version of a presentation to the Wiley Library Advisory Board, 18 November 1997.
