'Scott & his Scotland' (Pitlochry:K D Duval, 1971) and 'A Catalogue of Eighteenth Century Scottish Books (Falkland: K D Duval, [1964]).
Kulgin Duval and Colin Hamilton brought to their booksellers' catalogues a level of scholarship which lifted them to the level of reference works.
'A Catalogue of Eighteenth Century Scottish Books' was the first on which Kulgin and Colin worked together.
In the 'Creative lives' display, the National of Library of Scotland's 'working copy' is exhibited, which is in a sorry condition - an indication of the very heavy usage by Library staff.
