Two features introduced Two features introduced by Deweyby Dewey• Relative location - Dewey system
numbers books in terms of their relation to one another without regard to the shelves or rooms where they are placed
• Relative index - Brings together under one term the locations in the scheme of a subject which falls in several fields of study

The Dewey Decimal SystemThe Dewey Decimal System• Advantage: Orderly, hierarchical
system that organizes the universe of knowledge
• Disadvantage: Based on the decimal system. The real world isn’t neatly divided into tens (e.g. periodical table)
