The work was done by a New Hampshire Revision Commission, which describes what it did at the start of each volume of the RSA, and was ratified in 1955 by statute.
It was a sore spot with some lawyers that, to purchase law books, they had to do business with the arch-conservative Thomson.
[citation needed] The RSA endeavors to collect all the current laws "of a public and general nature" in a single, numbered set.
They let the reader determine the disposition of the previous codification (the RL) and of each enactment of the New Hampshire legislature: where that text was placed in the RSA.
In cases where source text was omitted from the RSA (for example, a law that is now obsolete or superseded by another), the disposition tables give the rationale.
