"This book records and interprets, in a narrative form, how groups of villagers and fisherfolk in Manila (Philippines), in West Bengal and Tamil Nadu (India) and in the states of Tlaxacala, Oaxaca and Michoacan and in a suburb of Mexico City (all in Mexico) tried to bring about social change through what one may call "people's communication". "People's communication" is a mode of communication which depends for its efficacy on people's energies rather than on technology." (Introduction)
