What is the Dewey Decimal System?

 

The Dewey Decimal System is one of libraries' oldest and most widely used organizational methods. Developed by Melvil Dewey in 1876, it is a system of classifying books in numeric order based on subject matter, allowing for easy access and retrieval of information.

At its core, the Dewey Decimal System is a three-digit number. The first digit of the number is separated into 10 divisions, with categories ranging from philosophy, religion, and social sciences to literature, science and technology, and fine arts. The second two digits are arranged to further pinpoint details and categorize subjects, such as birds, within the biology section. Finally, the broader divisions are followed by more specific classifications, making navigating the system easier.

The Dewey Decimal System has become an essential tool for libraries, providing an efficient and organized way for librarians to store and access information. The system is also helpful for library patrons, allowing them to quickly pull out books by subject and save time searching for specific information. Using numerical classifications, Dewey's system also provides an easy way for patrons to remember which books are located where.

Due to its timelessness and efficiency, the Dewey Decimal System is still widely prevalent and used today in libraries worldwide. Despite newer, computerized methods of indexing and cataloging, libraries still keep track of their material using this nearly 150-year-old system of numeric arrangement.

The Dewey Decimal System is a crucial tool in organizing vast collections of information and making it accessible. Its use in libraries has helped many to quickly find the book they're looking for, making the Dewey Decimal System an essential part of a library's infrastructure and an invaluable resource to library patrons.
