2. Library of Congress Classification (LCC)
Definition:
is a system developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries, and it 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.
Developed by:
The classification was invented by Herbert Putnam in 1897,

3. Library of Congress Classification (LCC)
Organization of resources :
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, ach 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, 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,

7. Dewey classification system:
Definition:
 is a proprietary library classification system first published in the United States by Melvil Dewey in The Decimal Classification introduced the concepts of relative location and relative index which allow new books to be added to a library in their appropriate location based on subject.

8. Dewey classification system:
Organization of resources :
Libraries previously had given books permanent shelf locations that were related to the order of acquisition rather than topic.
The classification's notation makes use of three-digit Arabic numerals for main classes, with fractional decimals allowing expansion for further detail. Using Arabic numerals for symbols, it is flexible to the degree that numbers can be expanded in linear fashion to cover special aspects of general subjects
arranged by discipline, not subject
for example :
topic like clothing is classed based on its disciplinary treatment,  within the conceptual framework

13. My preferred system for my library is :
I prefer to use Dewey classification system
Because it is depend on Arabic numbers and it can be expanded to cover every new book I add it to my library , also it classifies the books by displine and each has a specific number so it is easy to use.
