The record books, all manuscript volumes, are also "shrouded in mystery" to some extent. One volume records notarial acts involving city business during the period 1809-1824. The data is recorded on forms headed "Record of notarial acts executed by the City of New Orleans before ... the City Notary," but the records appear to have been compiled at some time after the date of the last act recorded. The record is an inventory of the various acts, showing date, "style of act" (sale, deposit, contract, etc.), "party thereto," "purpose thereof,", price, and remarks.

The second volume is made up of extracts from acts of sale for various properties located in the area comprising the city's second municipality during the period 1836-1852. The sales represented in the book date from ca. 1817-1841. The extracts may have been made by the notary for the second municipality or by some other officer interested in the titles of properties in the municipality. Each extract summarizes the original act of sale, much the same as in the deeds recorded in the Conveyance Office. Marginal notes, moreover, identify the streets on which the subject properties were located, a feature unique to this record book. This permits access to property sale records by the geographical location of the properties involved, access that is facilitated by a street name index at the beginning of the volume.

Volume three includes copies of notarial acts involving the New Orleans municipal government. Many are acts of sale in 1810 for parcels of the former plantation of Claude Treme. Among the other acts is one for the sale by the city of the land for Charity Hospital, various documents concerning the College d'Orleans, and one pertaining to a grant by the King to aid in the reconstruction of the Cabildo by Almonester following the fire of 1794. Of special note, attached to documents involving the property of Henry Metzinger, is the original grant of land by Carondelet to Metzinger in 1796. There is a typewritten inventory of these various acts at the front of the volume; this inventory has some defects (poor translations, incorrect dates) but it should be of some use as a finding aid.
