Railroad Commission of Wisconsin: Indexes to Central Files, 1905-1931 (Series 1252); Public Service Commission of Wisconsin: Index to Numerical Case Files and General Correspondence, 1914-1968 (Series 1255).
Additional point sheets list subjects in all files relating to more than one subject, with a decimal suffix added to the file number indicating each subject. The decimal suffix is a finding aid, not a subject code. Point sheets for the “C” files are in Box 637-639; sheets for the “D” files are in Box 739-740.
Because the most recent PSC correspondence, the E files, is poorly indexed by Series 1255, the Archives has prepared a separate list of titles by folder in order as boxed (using a numerical code), as well as an alphabetical sort of this list by titles. These lists are not yet available online but are filed with the registers in the Archives Division with the paper copy of this finding aid.
