Are you having trouble finding
books?
Melvil Dewey invented the Dewey Decimal Classification System.Melvil wanted a better way to arrange books in a library.
What’s the Idea Behind the Dewey System?
Melville sorted books by subject.
Epistemology Chemistry
Why is Dewey a Good System?
The Dewey Decimal Classification System allowed newly acquired books to be positioned in library collections based on their subjects. Formerly, books were positioned by date acquired.
DDCS introduced the concepts of relative location and relative index.
Dewey Numbers
Each subject begins with a number. How do we know which number goes with
which subject?
General Subjects Areas
The Dewey System
The Dewey System organizes or arranges non-fiction books by subject
597.98 TRU 973.313 FRE 811.54 SID
Non-Fiction NumbersNon-fiction numbers are arranged lowest to highest.
001 is before 002 512 is before 513
796 is before 797
Nothing comes before something!
How does DDCS work? Dewey divides all fields of knowledge into 10 main classes, each identified with three Arabic numerals. Fractional decimals allow expansion and refinement of topics.500’s = Math and Science 510 = General principles of mathematics 511 = Sets and graphs 511.3 = Set Theory
. 311 = Arithmetic / group theory
511.311 Abo If You Were A Set
Non-Fiction Authors
In the Dewey System, books on the same subject can have the same number, but different authors.
The first 3 letters of an authors last name help identify books.
