The original ringbinder was annotated as follows: "A-K, Research General, October 1979-closed February 1983", however there are letters outlying the start date, commencing in 1978 and finishing in 1983. Letters have been arranged alphabetically by researcher surname, subject surname, and/or organisation name. Original and copy letters are present.
