Prejudices/Bias Within The System

The Dewey Decimal System does in fact contain prejudice and bias. At the time the system was created, by founder Melvil Dewey, he created the 200 class. This category was to contain religion. Yet it has been argued that since Dewey was Christian the sub categories do not have enough information on other religions of the Eastern World.

In addition to Religious bias, the same type of bias is clear in the categories of History. At the time Dewey was only concerned with American History, and left out other parts of the world. Although this bias was present at the time of the systems creation, over the twenty revisions made by the system these bias' have since been adapted.

Obviously these prejudices and bias' have been worked on since the amount of libraries using this system still today is so high.
