THIS Catalogue contains all the books of the University Library, except those on Law and Medicine, and those on Agriculture, Botany, Chemistry, Geology, Mineralogy, and Natural History. It contains all the books in King's College Buildings, and also those of the Henderson, Melvin, and Wilson special Bequests in Marischal College Buildings. The books of these Bequests are entered without Press Marks on the margin. A few old Medical Works, which were in King's College Buildings, were not transferred with books on Law and Medicine to Marischal College Buildings, where, for the most part, there are duplicates of them, and therefore appear in this Catalogue.
