9.1 Identify the different  between Library of Congress Classification System (L.C.) and Dewey Demical Classification (D.D.C)

Answer :   The Library of Congress Classification (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. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC)

The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification. This system organizes books on library shelves in a specific and repeatable order that makes it easy to find any book and return it to its proper place.

Both of them originated in the U. S. A.; but they are different in nature and structure. Since LCC and DDC have been widely adopted by libraries outside their mother country, a comparison between them may be of interest to library patrons.

It was for a unique library that LCC was formulated. The special nature of the Library of Congress influenced the whole structure of the scheme. The Congress library consists of several collections, each housed separately; the resulting scheme is a series of individual classifications designed separately by subject specialists.
On the contrary, DDC is intended for use in all sorts of libraries of various sizes with abridged editions specially constructed for relatively small libraries of any type: public, school, and junior college libraries. It is the invention of one man, Melvil Dewey.

Differing from LCC, DDC is a hierarchical classification, applying the principle of development from the general to the specific in disciplinary and subject relationships. Notations display the hierarchical features in the lengthening of the basic number by one digit for successive divisions.

Chapter 1 " Data, Information, knowledge, and wisdom "


What is Data ? 


The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e. unprocessed data, refers to a collection of numbers, characters, images or other outputs from devices that collect information to convert physical quantities into symbols.


What is Information ?


Information in its most restricted technical sense is an ordered sequence of symbols that record or transmit a message. It can be recorded as signs, or conveyed as signals by waves. Information is any kind of event that affects the state of a dynamic system.


What is Knowledge ?


Knowledge is a familiarity with someone or something, that can include facts, descriptions, information, and/or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject.


What is wisdom ? 


Wisdom is a deep understanding and realizing of people, things, events or situations, resulting in the ability to choose or act or inspire to consistently produce the optimum results with a minimum of time, energy or thought. It is the ability to optimally (effectively and efficiently) apply perceptions and knowledge and so produce the desired results. Wisdom is also the comprehension of what is true or right coupled with optimum judgment as to action. Synonyms include: sagacity, discernment, or insight. Wisdom often requires control of one's emotional reactions (the "passions") so that one's principles, reason and knowledge prevail to determine one's actions.


What is Good Information ?


Information that can work on everywhere, useful, we need it, and in the right form.


Mind mapping


A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea.

Chapter 2 :The Quality of Information


1.Objective facts :

Objective means something that doesn't depend on what people think.
A fact is something that can be tested, measure or otherwise objectively concluded while a valid opinion is an interpretation of those facts, which means that in order to have an informed opinion you have to be familiar with the relevant facts.

Example : 

The world is a globe. This is an objective fact, since whether people think it is or is not, it's still a globe.

scientific facts are objective as are mathematical proofs; essentially anything that can be backed up with solid data.

2. Subjective Opinions :
 
Subjective is just the opposite. You can’t point to subjective subjects. They are all in your head and your past experiences. Subjective opinions are ephemeral and subject to any number of factors that can range from facts to emotions.

Subjective means something that does depend on what people think.

Example :

 - The Beatles were one of the greatest rock bands of all time. This is a subjective fact/opinion, since if everyone thought they were terrible then they wouldn't be called a great rock band (unless maybe you could show some external, biased reason why people thought they were awful, but without that incidental reason they would in fact be liked)

 - This is a subjective opinion.
A blue pen.

A: "The pen is blue no matter what."
Well that is wrong because the pen is only blue when it reflects sunlight, which consist of all the colours, and the reflection enters our eyes. If you put the pen under the light of another star which emits less colours, the pen won't be blue.
therefore saying the pen is blue no matter what is a subjective thought, as a more objective saying should be: The pen is blue under the sunlight from a normal functioning human eye.
But as you can see it is pretty long to say it objectively. So sometimes it is good to simplify things.
