Naturally, there is much diversity in the structure of the state codes, reflecting the diversity of the statutory law on which they were built. New York's codes are known as "Laws." California and Texas simply call them "Codes." Other states use terms such as "Code of name", "Revised Statutes", or "Compiled Statutes" for their compilations. California, New York, and Texas use separate subject-specific codes; Maryland's code has, as of 2016, been completely recodified from numbered articles into named articles; virtually all other states and the federal government use a single code divided into numbered titles or other top-level divisions. Louisiana is a unique hybrid in that it has five subject-specific codes and a set of Revised Statutes for everything else. A poorly drafted 1864 anti-corruption amendment to Pennsylvania's constitution prevented its legislature from starting comprehensive codification until 1970 (after the state constitution was finally amended to add the necessary exception in 1967).
