Western Cham is spoken in throughout central Cambodia and in the Châu Đốc area of An Giang Province, Vietnam, bordering the Cambodian border. Data was collected from 1969-1974 by Timothy and Barbara Friberg, much of which is from their main informant Kvoeu-Hor. The script is adapted from Vietnamese Quốc Ngữ orthography. Only 250 copies of the book were printed.
