This Technical Brief is the fourth in a series that addresses the issues of archaeological site stabilization and protection. Each of the previous Technical Briefs in the series has described a potentially useful technique for maintaining the integrity of an archaeological deposit. This one is about information exchange, which is part of the goal to foster interaction among governmental agencies, professionals, and the private sector. It is not a comprehensive guide to stabilization information; the several bibliographies that are available for different disciplines are better suited for that purpose. It also is not a substitute for contacting the agencies and professionals who have completed successful stabilization projects for detailed information. Rather, it is meant to provide a ready reference to sources that regularly collect and distribute information relevant to archaeological site stabilization. These sources can be useful starting points in stabilization project development as well as important references for comparing the merits of appropriate alternatives. It also should encourage those who are planning projects to seek a wide range of multidisciplinary data, since other professionals often are not aware of how important their knowledge and skills can be to preservation of non-renewable archaeological resources. -- CAL
