The Descriptive Inventory Index, a work in progress, serves as a searchable index of documents found in the vast City Archives collections. Documents in the archives have been divided into 234 descriptive Record Groups and many Sub-Groups for ease of storage and search ability. The documents contained in these record groups and sup-groups have been assigned to storage boxes with unique identification numbers. The Descriptive Inventory Index includes descriptions of all Record Groups and Sub-Groups as well as content descriptions of box numbers and a list of their contents.
