The section Political Movements and Parties (1968-2001) contains serials, monographs, small flyers, and pamphlets published by many of Chile's various political organizations. The publications in this section pertain not to specific political campaigns, but to other political activities and the year-to-year workings of the organizations.This section of this microfilm can seem particularly complicated, simply because of the ephemeral nature of political alliances in Latin America. Movements and parties may change their name, their logo, or their platforms repeatedly. The multi-party political system forces the continual re-negotiation of alliances among parties, and these alliances may be disbanded, reformed, or adjusted from year to year.An effort has been made throughout the microfilm to note relationships among various groups (e.g., Concertación de Partidos por la Democracia (see also Partido por la Democracia, Partido Radical Socialdemócrata, Partido Socialista de Chile)).
