About the Dewey Decimal System

The Dewey Decimal Classification system was created by Melvil Dewey, the librarian who founded the American Library Association. He first published his idea in an anonymous pamphlet back in 1876. He designed the system to lead one from the divine (philosophy and religion) through various human endeavors. It is a bit biased about some things (note that Christianity gets 90% of the religion listing, which is a bit like giving the US 75% of geography), and so is discouraged in some areas. Still, about 95% of school and public libraries in the US, as well as 135,000 libraries worldwide in 135 countries, use DDC. The majority of university and specialized libraries do not, however.

Another interesting thing to know is that fiction is part of the DDC. However, most libraries have such a large fiction collection that they choose to have it separately by author, rather than having a huge area of fiction in the middle.

The Online Computer Library Center of Dublin Ohio actually owns the patent on the DDC. It is regularly revised and updated to accommodate new subjects (for instance, the growth of computer science and the internet). If you look at a detailed chart of the classifications, you'll find that there are numbers that are not used yet to allow for expansion. It is currently undergoing its 15th revision.

One important thing to remember is that there are other classification systems in use. The United States Library of Congress uses a different system, and the Universal Decimal Classification , which is widely viewed as more complex but offering better, simpler classifications.


I have provided no answer sheet because the answers are pretty self-explanatory, and because there can often be more than one possible numbers. The best way to do this exercise is to guess at the answer using the list of subject classifications appropriate for your child, then look the subject up on your local library's website. If that service is not provided, then use that of another library, such as that of the New York Public Library.

And then, if possible, It's time for a field trip. Give the kids a list of the subjects you'll be studying in the next few weeks, plus any they really want to read about, show them how the local library is set up, and send them on their own Book Safari!
