SCDB data includes cases from 1791 term to the 2015 term. Many fields need to be mapped to their full values. The SCDB maintains an online codebook with these maps.
Martin-Quinn scores measure the relative ideology of a Justice or a Supreme Court term to the median Justice. Andrew Martin and Kevin Quinn wrote an excellent paper about the method.
Segal-Cover scores measure the ideology and qualification of an individual Justice before their appointment to the Court. Jeffrey Segal wrote a summary and shows the raw data as a table (warning: PDF).
