Our country is a place of several indigenous groups of people. These groups have their own cultural heritage to be unveiled. The unveiling of the Gaddangs refers to revealing and disclosing of their beautiful and interesting experiences. These experiences are revealed by their history which was derived from oral and written sources. Gaddangs have their own culture, innate strength, dialect and ancestral domain. There are several studies written by foreigners, such as Aduarte (1640), Sanders (1904), Beyer (1917), Malumbres (1918) and Herice (1960), which showed little information and disinformation about the Gaddangs. Local writers, like Gamboa (1960) and Lora (1984), dealt on the general culture of the Gaddangs. Some studies, like those of Lambrecht (1929), Keesing (1961), Mariano (1965), Wallace (1967) and Scott (1980), dealt on ethno-history that considered patterns of settlements, economic activities, which are interrelated with ecological factors. Literature tackling the historical as well as socio-economic development of the Gaddangs, though scarce, were described by Salgado (2000), Tejon (1982), Fenanadez and Juan (1919) and Gainza (1849). -Blurb from the Preface.
