During the annual legislative sessions, the language of the statutes is amended to reflect changes contained in the public acts passed by the legislature. This process of codification is one of the responsibilities of the Legislative Commissioners' Office (LCO). LCO produces several useful resources to help users correlate public acts and statutes, including reference and conversion tables.
In addition to these regular changes, the organizational structure of the statutes as a whole is also occasionally changed; this is referred to as a revision and is usually accompanied by the year. Revisions once occurred with greater frequency, but the last major revision to the General Statutes of Connecticut occurred in 1958, which would simply be called the 1958 Revision. Since that time, several of the titles have been moved or repealed, but the overall structure has remained intact.
