Classification and Arrangement of Books in the Library * The Dewey Decimal Classification Scheme * is a proprietary library classification system created by Melvil Dewey in 1876. It has been revised and expanded through 23 major editions, the latest issued in 2011. Dewey was responsible for all revisions until his death in 1931. A designation number, such as Dewey 16 for the 16th edition, is given for each revision.

* A library assigns a DDC number that unambiguously locates a particular volume to within a short length of shelving which makes it easy to find any particular book and return it to its proper place on the library shelves. ] The system is used in 200,000 libraries in at least 135 countries * Books are arranged on the shelves according to the Dewey Decimal Classification (DDC), which groups the fields of knowledge into 10 main classes, namely: 000 – 099| General works| 100 – 199| Philosophy and related fields| 200 – 299| Religion| 300 – 399| Social sciences| 400 – 499| Languages|

500 – 599| Pure Sciences| 600 – 699| Applied sciences (Technology)| 700 – 799| Fine Arts| 800 – 899| Literature| 900 – 999| History, geography, biography| * The Library of Congress Classification Scheme * The Library of Congress Classification (LCC) is a classification system that was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. Over the course of the twentieth century, the system was adopted for use by other libraries as well, especially large academic libraries in the United States.

It is currently one of the most widely used library classification systems in the world. The Library’s Cataloging Policy and Support Office maintains and develops the system, posting weekly lists of updates on its Web site. * The system divides all knowledge into twenty-one basic classes, each identified by a single letter of the alphabet. Most of these alphabetical classes are further divided into more specific subclasses, identified by two-letter, or occasionally three-letter, combinations. For example, class N, Art, has subclasses NA, Architecture; NB,Sculpture, ND, Painting; as well as several other subclasses.

Each subclass includes a loosely hierarchical arrangement of the topics pertinent to the subclass, going from the general to the more specific. Individual topics are often broken down by specific places, time periods, or bibliographic forms (such as periodicals, biographies, etc. ). Each topic (often referred to as a caption) is assigned a single number or a span of numbers. Whole numbers used in LCC may range from one to four digits in length, and may be further extended by the use of decimal numbers.

Some subtopics appear in alphabetical, rather than hierarchical, lists and are represented by decimal numbers that combine a letter of the alphabet with a numeral , e. g. .B72 or . K535. Relationships among topics in LCC are shown not by the numbers that are assigned to them, but by indenting subtopics under the larger topics that they are a part of, much like an outline. In this respect, it is different from more strictly hierarchical classification systems, such as the Dewey Decimal Classification, where hierarchical relationships among topics are shown by numbers that can be continuously subdivided.

* Non-fiction books are arranged on the shelves from left to right, top to bottom, according to the following: 1. Class numerically according to DDC number 2. Same class number 3. Alphabetically by title, if with the same class and author number * Fiction books (Novels particularly in pocket books) have no class numbers. They are alphabetically arranged on the shelves by author numbers.

Card Catalogue * A card catalogue is a physical listing of all of the contents of a library, organized with a single cardfor each item in the library. It was a familiar navigational hazard and blessing in all libraries well through the late 20th century, when physical catalogs began to be displaced by computerized versions.

Some libraries have kept them, often as sentimental mementos, and a few actively maintain their listings, although this is most common in small, remote libraries. * The need to catalogue books in some way has been present since they were invented. A good catalog enables people to know which publications a library has and where to find them, and many contain additional information that could be assistance to scholars. Early library catalogs were kept on scrolls or in ledgers, and they were often printed and distributed so that distant scholars could know which books a library had.

* The concept of the card catalogue was introduced in the 1800s, and it was a great help to scholars. These catalogs can be configured in a number of ways, and their organization makes it easy to add or remove books, and to find particular ones. Every time a new book enters a library, a card is created for it, with information like the title, author’s name, subject, and location of the book. * The definition is: A library catalog (or library catalogue) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations.

A card catalog is a list of the books in the library on 3×5 cards. Each book is listed on one or more cards. A card has a listing for Author, Title, and Subjects. The Cards are arranged alphabetically in drawers. Someone had to alphabetize and file each card by hand. In large university libraries several people would be doing this work at once. This information is now on computers. In a few seconds the computer alphabetizes and files the work that took humans all day. D. Sections of the Library.
