The records in the CLRO are thought to be one of the finest and most complete municipal archives in Europe. However, researchers may notice some substantial gaps and these merit an explanation. The majority of the records of the Freedom of the City prior to 1681 and the City's Cash accounts prior to 1632 were either destroyed in the Great Fire in 1666 or in another fire in the Chamber (the finance department of the Corporation) in 1786. Similarly, it is thought that a fire at the Sessions House in the Old Bailey in 1877 destroyed the early Sessions minutes and files, as well as the bulk of the supporting papers. The paucity of surviving Sheriffs' Court records for the medieval period is thought to be because these records were considered to be the personal property of a Sheriff, who might be called upon to produce records in order to account for his actions during his time in office long after his Shrievalty had ended. Similarly, it is thought the records of coroner's inquests have not survived in any quantity before 1788 because inquests were not held in a court building until relatively recently, and so the records of inquests were considered part of the personal papers of office holders rather than administrative records.
