This should help you! Good Luck!!

Answer 2

It is a library system for cataloging/organizing books. The numbers you see on the side of the book are the dewey decimals. They are catagorized like this:

000 – Computer science, information, and general works
100 – Philosophy and psychology
200 – Religion
300 – Social sciences
400 – Language
500 – Science
600 – Technology
700 – Arts and recreation
800 – Literature
900 – History and geography

The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876

Its actually quite complex when you get into the sub categories.

Answer 3

The Dewey decimal system is a system for cataloging and shelving library books, so they are easy to find.
Think of it as a postal system, where each block specializes in a different kind of books, and, just like the postal system, each block has a different number.
That's what the Dewey system does.
There are many different categories, ranging from anthropology through biology, cooking, dancing, etc.etc. and subcategories within those broad categories.

If you google up Dewey decimal system, you'll find several sites that will explain each and every category.

Many libraries use Dewey only for non-fiction and catalogue fiction by broad classifications (murder mysteries, chick lit, adventure) and shelve alphabetically by author's surname.

Answer 4

The DDC attempts to organize all knowledge into ten main classes. The ten main classes are then further subdivided. Each main class has ten divisions, and each division has ten sections. Hence the system can be summarized in 10 main classes, 100 divisions and 1000 sections. DDC's advantage in choosing decimals for its categories allows it to be both purely numerical and infinitely hierarchical.

It also uses some aspects of a faceted classification scheme, combining elements from different parts of the structure to construct a number representing the subject content (often combining two subject elements with linking numbers and geographical and temporal elements) and form of an item rather than drawing upon a list containing each class and its meaning.

Except for general works and fiction, works are classified principally by subject, with extensions for subject relationships, place, time or type of material, producing classification numbers of not less than three digits but otherwise of indeterminate length with a decimal point before the fourth digit, where present (e.g. 330 for economics + 9 for geographic treatment + 4 for Europe = 330.94 European economy; 973 for United States + 05 form division for periodicals = 973.05, periodicals concerning the United States generally).

Books are placed on the shelf in increasing numerical order; the whole number to the left of the decimal is in counting order, while the digits to the right of the decimal are compared one digit at a time, with a blank coming before zero. (Example: 050, 220, 330.973, 331 etc.) When two books have the same subject, and therefore the same classification number, the second line of the call number, which usually has the first letter or first several letters of the author's last name (or the title if there is no identifiable author), is placed in alphabetical order.

It is a common misconception that all books in the DDC are non-fiction. The DDC has a number for all books, including those that generally become their own section of fiction. If DDC rules are strictly followed, American fiction is classified in 813. Most libraries create a separate fiction section to allow shelving fiction in a more generalised fashion than Dewey provides for, or to avoid the space that would be taken up in the 800s.

Answer 5

How some libraries are aranged.
Basically there are 10 different main classes. Then they are further divided every class has 10 divisions and each division has 10 sections. Basically there are 10 classes, 100 divisions, and 1000 sections. The advantage is to have it numerical and have the advantage of being able to just about infinetly increase if the need arises.

Answer 6

its the numerical assignment of a number(usually to the 1000th of a decimal) to archive the books on the shelves for easy finding.
