Abstract
Salient node notation is a technique for decreasing the average length of notation in a classification scheme without sacrficing expressiveness or disturbing the succession of chracteristics of the filing order. Assignment of notation begins at a node of the classification tree other than the root. This salient node may be determined algorithmically, given data on the bias of the collection to be classified, even if only part of the tree has been developed. A dummy value is reserved to indicate upward movement in the tree. The technique is especially applicable to classification schemes for spevialized collections and to facets such as space in which the biases of human existence are especially prominent
