The Library of Congress is the worlds' - or one of - biggest library, situated in America. The Dewey Decimal System is a common library system, organising non-fiction books by numbers, and placing them in certain areas, then putting their according number in an alphabetized folder with the subject and it's number.
The Dewey Decimal Classification system organizes books by subject into 10 main classes with numerical subdivisions, while the Library of Congress Classification system groups books by subject into 21 main classes with alphanumeric subclasses. The Dewey system is more commonly used in public libraries, while the Library of Congress system is favored by academic and research libraries in the United States.
The Dewey Decimal System classifies books according to ten broad classes:
000 - Computer science, Library and Information science & general work
100 - Philosophy and psychology
200 - Religion
300 - Social Sciences
400 - Language
500 - Science
600 - Technology
700 - Arts
800 - Literature
900 - History, geography & biography
Each class is broken down into ten divisions (e.g. 110, 780, 940), and each division is broken down into ten sections (e.g. 115, 781, 943). These whole numbers can then be followed by a decimal point and one or more digits to further specify the topic of the book. Most public libraries and school libraries use the Dewey Decimal Classification system.
For example:
610 = Medical sciences
610.6 = Professions
610.69 = Medical personnel
610.695 = Specific kinds of medical personnel
610.6952 = Physicians
610.69520942 = Physicians in England and Wales
610.6952094205 = Physicians in England and Wales 1485-1603
This number is then followed by the first three letters of the author's last name.
The Library of Congress System (aka Library of Congress Classification System, or LCC) uses a series of one letter (corresponding to a specific main class), followed by an optional second or third letter (to designate a subclass, if applicable), followed by one or more numbers. After this, the date of publication is added. This particular system allows for better articulation of the subject of a book, and is typically used in academic libraries.
The main classes are:
A -- General Works
B -- Philosophy. Psychology. Religion
C -- Auxiliary Sciences of History
D -- World History and History of Europe, Asia, Africa, Australia, New Zealand, Etc.
E -- History of the Americas
F -- History of the Americas
G -- Geography. Anthropology. Recreation
H -- Social Sciences
J -- Political Science
K -- Law
L -- Education
M -- Music and Books on Music
N -- Fine Arts
P -- Language and Literature
Q -- Science
R -- Medicine
S -- Agriculture
T -- Technology
U -- Military Science
V -- Naval Science
Z -- Bibliography. Library Science. Information Resources (General)
For example: under the main class "Z" [Bibliography. Library Science. Information Resources (General)] is the subclass "ZA" [Information resources (General)].
Cutter numbers are also used to further narrow down the subject in terms of geographic names, personal or corporate names, topics, or titles. These are added after the class designation. More than one cutter number can be added to a call number.
For example:
To designate the geographic name "Columbia County, New York", you would add N7 (which is for New York), then the number 2 (which is for Columbia County).
Thus, for a book on the history of art in Columbia County, New York, the class number would be: N6530.N72
The Library of Congress is the United States' Library. Its the oldest library, started by the federal government, and helps with research that congress does. The library is the worlds largest library and holds some of the oldest books in the world. While the Dewey Decimal System is the system used to organize books in the library, it was created by Melvil Dewey in 1876. Its still used today and has only been revised 22 times since it has been created.
Different between LCC and DDC
The Library of Congress Classification (LCC)
The LCC is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries, for example, Australia and Taiwan, R.O.C.. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC).
Listed below are the letters and titles of the main classes of the Library of Congress Classification.
Letter

A
General Works
B
Philosophy, Psychology, and Religion
C
Auxiliary Sciences of History
D
General and Old World History
E

G
Geography, Anthropology, and Recreation
H
Social Sciences
J

N

P

Q

R

S
Agriculture
T

U
Military Science
V
Naval Science
Z
Bibliography, Library Science, and General Information Resources
Dewey Decimal Classification System (DDC)
The DDC attempts to organize all knowledge into ten main classes. The ten main classes are each further subdivided into ten divisions, and each division into ten sections, giving ten main classes, 100 divisions and 1000 sections. DDC's advantage in using decimals for its categories allows it to be purely numerical, while the drawback is that the codes are much longer and more difficult to remember as compared to an alphanumeric system.
Classes listed
The system is made up of seven tables and ten main classes, each of which are divided into ten secondary classes or subcategories, each of which contain ten subdivisions.
The tables are:
· standard subdivision
· areas
· subdivision of individual literatures
· subdivisions of individual languages
· racial, ethnic, national groups
· languages
· persons
The classes are:
· 000 - Computer science, information and general works
· 100 - Philosophy and psychology
· 200 - Religion
· 300 - Social sciences
· 400 - Language
· 500 - Science (including mathematics)
· 600 - Technology and applied Science
· 700 - Arts and recreation
· 800 - Literature
· 900 - History, geography, and biography

Dewey Decimal is the classification system of the library.
both are used by academic libraries. both hierarchical hence arrangement is order. both contain old books.
The four main conflicts in the Dewey Decimal System are between different classification systems (e.g., Dewey Decimal vs. Library of Congress), between traditional print resources and newer digital resources, between universal standards and local adaptations, and between subject-based categorization and interdisciplinary approaches.
A library catalog is a list of materials held by the library, providing information on their availability and location. Classification, on the other hand, is the systematic organization of library materials based on subject categories, allowing for easier browsing and retrieval of materials within the library's collection. In essence, the catalog tells you what the library has, while classification tells you where to find it.
The exact numbers depend on which university library and the age of the information you access, but generally there are between 40 and 200 different daffodil species and over 25,000 registered cultivars divided among the 13 divisions in the daffodil classification system.The exact numbers depend on which university library and the age of the information you access, but generally there are between 40 and 200 different daffodil species and over 25,000 registered cultivars divided among the 13 divisions in the daffodil classification system.

difference between knowledge classification and book classification?
They are not the same. Here's an answer from the Library of Congress: http://www.loc.gov/rr/scitech/mysteries/sweetpotato.html
The Dewey Decimal Classification system and the Colon Classification system are both library classification systems, but they differ in several ways. Dewey Decimal is a numerical system that categorizes materials based on subject while Colon Classification is an alphanumeric system that organizes materials based on facets of subjects. Dewey Decimal is more widely used in public libraries while Colon Classification is more commonly used in academic libraries. Ultimately, the choice between the two systems depends on the specific needs of the library and its users.
Members of Congress often have ideas very different from the president about what constitutes desirable public policy.

Scientific classification is written in Latin to avoid confusion between scientists that speak different languages than one another.
classification paragraph takes a topic and classifies it into different categories, while the example paragraph gives examples of one thing.
