This subseries (18.48 linear feet) documents civil liberties concerns within various states and U.S. Possessions. There are also a few folders documenting civil liberties concerns in Canada. Prior to creating a state affiliate network, the ACLU had "state correspondents"--individuals who monitored civil liberty concerns within their state and informed the national office of local cases and issues. More extensive for earlier years, prior to the growth of the state affiliates, the files are organized chronologically and then alphabetically by state within each year. Large cases or issues of concern are contained in their own folders; many minor issues are grouped a general folder for each state. Correspondence comprises the majority of this subseries, but briefs and printed matter are also found.
