This lot is from the collection assembled by a man who pursued a lifelong interest in speleology - the study of natural cave systems and he sought out important books on the subject ranging from 18th century classic works to rare pamphlets and offprints. The first book apparently acquired, by way of a gift from a family friend in 1955, when he was living as a young man in Australia and exploring the famed Jenolan Caves in New South Wales. For over fifty years, as he moved around the world, his interest expanded into USA cave systems and those in the United Kingdom and Europe. Many of the books have a pedigree of previous ownership and almost all are accompanied by meticulous index cards that record not only the full bibliographic information for each book but also when, where and from whom it was acquired, together with the price paid; the cards are often punctuated with pithy personal comments that show clearly the depth of interest in the subject. The collection represents an unrivalled opportunity today for collectors and others to acquire rare and important works.
