Question: Comparative history of protest in U.S. 1960s - present

Is there already a comparitive timeline detailing and explaining the ebb and flow of social movements, specifically social justice and animal rights, within the U.S.? If not, what kind of data is there on the major protest movements in the U.S. between 1960 - present?

The overall goal of my factfinding is to try and gauge whether or not the fairly recent emergence of animal rights groups such as PETA, and the animal rights movement as a whole, has coincided with a decline in participation in human rights causes.
