The books listed at the bottom were generally more helpful to me than the websites.  I'm providing the links for your convenience, but I also encourage you to visit your local library and get your hands on some good old-fashioned hard copy volumes.

Websites about some of the groups and organizations I honor in my "Mushrooms" patch (many sites are available only in Spanish, as I note in the descriptions):

http://www.madres.org/ - official website of the Asociación Madres de Plaza de Mayo (Mothers of the Plaza de Mayo), the Argentinian women who for over 25 years have been demonstrating and searching for their sons (and other family members) who were disappeared by the military junta of the late 1970s.

http://www.wamani.apc.org/abuelas/ - official website of Abuelas de Plaza de Mayo (Grandmothers of the Plaza de Mayo), women who attempt to locate their grandchildren who were either kidnapped with their parents or were born in captivity in the late 1970s.

http://www.famdesapcba.org.ar/Hijos.htm - HIJOS (Hijos por la Identidad, la Justicia, contra el Olvido y el Silencio) are mostly children of the disappeared of Argentina fighting for human rights.  This website (only in Spanish) is part of a larger one of relatives of the disappeared in Argentina.

http://www.desaparecidos.org/fedefam/ - I believe this is the official site for FEDEFAM (Federación Latinoamericana de Asociaciones de Familiares de Detenidos-Desaparecidos, or Latin American Federation of Associations of Relatives of the Detained-Disappeared), an umbrella organization that has linked many groups throughout Latin America.  The website does not seem current, but has a lot of information about FEDEFAM's history.

http://www.comune.bologna.it/iperbole/asssolbg/gam.html - official website (only in Spanish) of Guatemala's Grupo de Apoyo Mutuo (Mutual Support Group) that originated in 1984 to help find disappeared family members.  This website is not current.

http://www.igc.org/beijing/ngo/closet.html - El Closet de Sor Juana is a Mexican group of women of all sexual orientations working together for their political and social rights.  I could not find an official website, but this provides an in-depth description of the organization (only in Spanish).

http://www.geocities.com/vasodeleche2001/ - one of many websites (only in Spanish) for Vaso de Leche (Glass of Milk), a grassroots Peruvian effort that began with a few women deciding to provide all children with a glass of milk a day, since the government was not doing so, and grew into a movement.  

http://www.geocities.com/sihuat/conamus.htm - official website (only in Spanish) of El Salvador's CONAMUS (Coordinadora Nacional de la Mujer Salvadoreña), a nonprofit that organizes around political, social, and economic issues for women.
