The trends and their consequences will reveal themselves over time and will undoubtedly depend on archaeological research and results , the cooperation of researchers in other places and countries , the training of quality professional archaeologists , the protection of sites and their materials , and the use of archaeology in a world where cost has to be a primary consideration in research and conservation . While the AAPP is a full-scale excavation , it is also a University of Bradford field school , training students in all aspects of archaeological method and methodology . Besides archaeological mapping and the creation of an impressive inventory of archaeological sites in Canada , Harlan I. Smith was a pioneer in ethnographic film-making , anthropological photography and museum education . Recent reviews of microbial degradation have been published ( Blanchette et al. 1990 ; Eriksson et al. 1990 ; Highley and Illman 1991 ) , and this information can be used as criteria to evaluate decay in archaeological wood and other wood of historic value ( Blanchette et al. 1990 ; Blanchette et al. 1991b ) . As Guidi notes in his recent book on archaeological methods , reconstructions used to be considered less important than other forms of archaeological activity and were thought to be mainly useful in teaching and site presentation ( Guidi 1999 : 103 ; for a good example see Clark et al. 2003 ) .
