Hypertexts constitute a very practical computer system for the consultation of texts, allowing users to obtain quick information on the subjects of interest thanks to logical association links. In addition to that, multimedia hypertexts give you the possibility to look up pictures, maps, drawings and any audio/video material for a thorough and immediate understanding of the subjects dealt with in the texts.

The whole of these features make multimedia hypertexts important tools for the preparation of training courses for operating elaborate systems, and for presenting, recording and exhibiting projects and interventions on both architectural and urban levels.

The documentation and communication activities for interventions on areas having a special artistic-historical value have a double effect. First, they allow to record with precision all interventions and working stages (in order to facilitate future historical research) and – secondly – they help to promote and exploit these sites for tourism and advertising, which can be done even by means of a web site on the Internet.

It is also worth pointing out the development of special software for consultation/examination of data and documents. Thanks to laptop computers, this technology can be used in building sites too, and even unskilled workers can easily access, display, and print out data.
