Originally housed in a ringbinder this file is a counterpart of Acc.13328/1647. The original ringbinder was annotated as follows: "A-K, Researchers Correspondence, January 2003", however there are letters outlying this date, beginning in 2000, and finishing in 2009. Letters have been arranged alphabetically by researcher surname, subject surname, and/or organisation name. Original and copy letters are present. A manuscript index for the original contents of the ringbinder is present in file D-K at Acc.13328/1647.
