|Administrative history||Some items, such as SBHB/WO/2/10 and SBHB/WO/2/11, probably pre-date the existence of the Works Department, and so may have originated in other predecessor departments. They have been retained with the departmental records having been transferred from the Works Department, and probably been in use there.|
|Arrangement of the records||Records of the Works Department were formerly catalogued as SBHB/HA/29, many items from which had been destroyed in 1979 and 1992, following appraisal. The remaining items were recatalogued in 2015 when the original card catalogue entries were transferred to the Calm database.|
Three files relating to works at Gloucester House, formerly catalogued as HA/29/1/11 and HA/29/2/12, were loaned to P. Byes from the Estates Department on 25 Aug 1988, and never returned. They were presumed missing in 2007, and not included in the recataloguing of material in 2015.
