Abstract:

Microsoft’s specification for 'Longhorn' Help represents a major revolution in user assistance development for the Windows platform. Instead of simply refining the technical infrastructure of Help (windowing, links, search, etc.), Microsoft has given a good deal of thought to the needs of both Help authors and end-users.
