The records are printed proclamations (many with woodcuts of Laussat's official seal or other figures) and decrees issued and signed by Laussat, along with manuscript letters and other documents transmitted by him to the Council. Included are Laussat's proclamations of possession of the province, of the establishment of the municipal government, and of the appointment of numerous provincial officials. The image to the right is of Decree No.436 by Lausset establishing a municipal government for French New Orleans.

Also included in this collection are documents relative to issues that came before the Prefect for disposition. These range from the December 17, 1803 decree for the superintendence and discipline of enslaved people in Louisiana, to a January 20, 1804 letter concerning an investigation of the former treasurer, Juan de Castanedo. Of special interest is an inventory, dated December 10, 1803, of the archives of the Spanish Cabildo turned over to the municipal government on Laussat's order.

Researchers should view the combined inventory of the letters, petitions, and decrees from the Cabildo, Conseil Muncipal, and Conseil de Ville (1770-1835) for more information about about these volumes.
