Formal: If the material being described already has a formal title, use that, copying it word-for-word. Formal titles seldom exist at the fonds and series level. To be a formal title it must be on or in every single item in the unit. Thus formal titles are usually only found at the item level and are most common with non-textual records.
Supplied: If there is no formal title, supply one based on the contents of the fonds, sous-fonds or series. The supplied title is composed of a name element (usually the creating individual, family or organization) and a word or phrase that gives the nature of the archival unit. For fonds, use the name of the creating entity plus the word "fonds" (Examples: "City of North Battleford fonds"; "Joe Smith fonds"; "Jones Family fonds")
As for the series and sub-series level, identify the contents of the unit and type of records (Examples: "Bishop's Correspondence" or "Executive Committee Minutes.")
