How the Library is Arranged (Chart)

Books and CDs are arranged on the shelves using the Dewey decimal classification scheme so they may be easily retrieved. A Dewey class number denotes a subject, and expresses its relation to other subjects. For example: a book with the class number 320 (political science) would be shelved before another at 320.5 (ideology, a concept in political science), which would be shelved before another at 320.51 (liberalism, an ideology).

The Dewey decimal classification is a system of library classification made up of ten classes, each divided into ten divisions, each having ten sections. For example, class 600 ("Technology") includes division 630 ("Agriculture and related technologies"), which includes section 636 ("Animal husbandry").The numbers are between 000 and 999. The hundreds represent broad topics, the tens represent subtopics, the ones represent sub subtopics, and the decimal places represent sub topics, and so on.
