How to find information books in the library
Information books help you to discover facts.
In the library, each non-fiction/information book has a number on its spine. This is a code number for the subject of the book. Books on the same subject have the same number.
Information books are put on the shelves in number order. That way, books on the same subject are shelved together.
This code number is more usually called a class number, Dewey number, or subject number.
Dewey Decimal Classification
We follow a plan worked out over 100 years ago by Melvil Dewey. He decided on 10 main subjects, each of which has a range of numbers:
|General Knowledge (encyclopaedias, etc)||0 to 099|
|Philosophy (why we are here, how we should live our lives)||100 to 199|
|Religion (what people believe)||200 to 299|
|Social Studies (how we organise, e.g. politics, education)||300 to 399|
|Languages (how people talk and communicate)||400 to 499|
|Science (the natural world, e.g. plants and animals)||500 to 599|
|Technology (the uses of science, e.g. cars)||600 to 699|
|Art, Hobbies and Sport||700 to 799|
|Literature (e.g. poems and plays)||800 to 899|
|Geography (places), Biography (people) and History (the past)||900 to 999|
Within a subject, the more specific you get the more specific the number becomes, e.g. poetry is a part of literature (800 to 900) and can be found starting at 821.
Find an information book on any subject
- Look for your subject using the catalogue on the Information Point or ask to use the “Children’s Subject Index”, which has a list of the subject numbers
- Look at the number next to your subject, e.g. animals - 591
- Go to the shelves and find the books with this number on the spine.
