Testing is an open-ended process.
It is unavoidable that any web site as large as that stored on the CD-Rom of WMC'99, will contain errors. All one can hope for is that the number of errors remains relatively small. The production of this CD-Rom was a pilot project. It was the first time that a CD-Rom was produced for an entire Western MultiConference. A first CD-Rom must be burnt before full testing can take place.
