The items listed in this catalogue were almost all taken from the G. Ross Roy Collection of the University of South Carolina's Special Libraries Division. As the reader may be aware, collecting the works of MacDiarmid is made particularly difficult because there is no bibliography, or even checklist, of his complete works. Dr. W. R. Aitken has produced a useful list of books by or edited by MacDiarmid, but much of his work is to be found only in the periodicals and books to which he contributed. While particular attention was paid to works entirely by MacDiarmid in the selection of works to be displayed, the Roy Collection is rich also in works edited by MacDiarmid, or to which he wrote introductions or contributed essays or poems. It contains virtually the whole of the MacDiarmid canon, with significant variant issues of major works. and two important series of presentation inscriptions of books presented by MacDiarmid to his wife, Valda Trevlyn, and to Ross and Lucie Roy.
