What is the Dewey Decimal Classification System?

The DDC System is a numeric system used by most libraries to organise their information resources (books, journals, etc.) in subject groups, so that they are easily accessible to users.

For example:

Since all the books on Mathematics will have the number 510, the books will all be at the same shelf location. This means that you can go to that shelf location and browse all the mathematics books easily. When you do a search on the OPAC (the Library online catalogue), you will find the Call Number of the item next to each record.

It is very important to understand the Dewey Decimal Classification system in order for you to be able to find the items in the Library.

An example of a Dewey nr. (location) on the spine of a book. The number 005.72 YOU indicates the location of the book in the Library.
