This series contains a set of cards that acts as an index to the council minutes for 1938-1965. The cards are organised into two alphabetical sequences covering 1938-1950 and 1950-1965.
The cards provide an index to both council and committee minute books. The page references are prefixed with a letter to indicate which minute book the page is in:
- C - Ordinary Council
- W - Works Committee
- F - Finance
- R - Reserves
Smaller committees have their own specific cards.
