Hand-written logs of photos were kept by the photographers. There are a number of issues: they did not always know exactly what they were photographing so some comments are very vague ("NIRNS progress" is a favourite); it is not always easy to read the handwriting; from 1964 rubber-stamped index numbers are of deteriorating clarity towards the end of each stamp's lifetime; some photo series numbers are duplicated; and some photos have been taken for use by individuals so are not documented at all which makes dating them inaccurate.
