Dewey Decimal System

Melvil Dewey's amazing hundreds groups
for (mostly) non-fiction

Legend says that Dewey was able to classify all human knowledge into 9 very
general categories by thinking like a"primitive caveman who asked himself questions
about the world around him. The answers to these questions"systematically"led him
to"acquire knowledge as he explored the world around him. Later, during this process,
the caveman"was able to determine what was important in his own life and
in the lives of his fellow cavepeople.
