The Dewey Decimal System
library is arranged according to the Dewey Decimal System. In
1876,Melvil Dewey decided to make finding library books easier. Up
until then each library had a different system and only librarians
find books because it was so complicated. Dewey believed that everyone
should be able to use libraries for themsleves so he organised books
into 10 categories according to the questions they answered about
the world and gave each category a number. This became known as the
Dewey Decimal System, which is still used in libraries across the
These categories can be be sub-divided further. For example the 340's in the social sciences category have books about law.
Non-fiction books are arranged by their Dewey number, and then by the author's surname.
