How does the Dewey decimal system work?

It works with numbers. You put the number in the category on the book in that same category.

The Dewey Decimal System of Classification organizes the Lincoln Library's book, video, DVD, and CD collections. Items are catalogued and classified first by topic and then secondly within a topic, and finally given a unique number. This enables you to find materials easily anywhere in the collection.

For example, the book Equine Photographs and Drawings for Conformation and Anatomy is assigned call number 636.1 Eq57, which falls under the heading Applied Sciences/Agriculture. Additionally, you can browse that section of materials to find additional materials on the topic. Use the Library Catalog to search for a title, author, or subject.

The call number will be given next to Location on the screen. Write down the call number (as in the above example: 636.1 Eq57), and go to the shelves for that item and similar items. For a breakdown of the system and its call number assignments, see this online Dewey Decimal chart.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
