Students for a Libertarian Society was founded in 1979 as separate entity from the Libertarian Party which already had a youth section. The SLS, with a central location in San Francisco, California published pamphlets and a newspaper/magazine titled Liberty. Among a few others Jeffery Freidnman (a Brown grad) served as one of the groups national presidents. The SLS was fairly short lived having mostly disbaned by 1983.  Libertarianism has become more prominent in recent years in American politics, but many politicans associated with the ideology are not actually offiliated with the Libertarian Party.
In the post today there is an undated pamphlet, which provides basic information about the group and the positions they hold. In general the SLS promoted small government and individual rights.
