These two volumes are the first of a major series of catalogues planned to cover the Balinese manuscripts in the Leiden University Library and other Dutch collections. They run on from the four volumes of Th.G.Th. Pigeaud's Literature of Java, (1967–1980), but in view of the very distinctive character of the materials described here by Dr. Hinzler, the presentation is quite different. Part 1 contains full-page illustrations of each of the 483 Balinese drawings in the Van der Tuuk Collection, together with a gallery of 50 photographs, mostly of temples and dancers for comparison with certain of the items in the collection. Part 2 begins with an historical, critical and technical introduction, followed by a detailed, self-contained description of each drawing, and where required, its literary background and reference, each entry running to one, two or more pages. The Collection is numbered Cod. Or. 3390.1–307 and 17994.1–3.
