Includes minutes, correspondence, administrative papers and drafts of the 'Stair memorial encyclopedia'. Note that no attempt has been made 'to weed' the various drafts; this is to allow researchers to compare draft against draft and so follow each expert’s 'train of thought' in particular fields. For any particular area of interest, all the folders/files relating to the subject should be consulted. In items 322-366, particularly, there are extensive drafts and re-drafts of titles with accompanying proofs, amendments and any related correspondence.
