*   Identify the different between Library of Congress Classification System (LC)
 and Dewey Demical Classification system (DDC)


                 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, 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)
                                 
                 The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876.
It has been greatly modified and expanded through 23 major revisions, the most recent in 2011. 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. The system is used in 200,000 libraries in at least 135 countries.
A designation such as Dewey 16 refers to the 16th edition of the DDC.

OBJECTIVITY & SUBJECTIVITY
The difference between these two important ideas is the difference between fact and opinion. Facts are objective and provably true; however, if no clear facts exist about a topic, then a series of balanced opinions needs to be produced to allow the reader to make up his or her mind; opinions are subjective ideas held by individuals and so are always biased. If unbalanced opinions are presented as if they are facts, they act as propaganda or persuasion, e.g. a newspaper headline might state: "Youngsters are the prime cause of trouble in this area". This is presented as an objective fact but is clearly a subjective opinion.
Factual , based on observation, etc.
Like :

Subjective; The father said he "feels really sick" today.
Objective: The father appears to be pale and he has a red, raised rash on his arms and legs.

An objective fact is a non-biased statement. That is basically stating something with fairness, and not having a personal opinion about it. There are usually objective facts stated all the time on the news.

Information Society

      The Information Society is a society in which the creation, distribution diffusion, use, and manipulation of information is a significant econamic, political, and cultural activity. The knowledge ecnomy is its economic counterpart whereby wealth is created through the economic exploitation of understanding

      The Information society  is to gain competitive advantage internationally through using IT in a creative and productive way. An information society is a society in which the creation, distribution, diffusion, use, integration and manipulation of information is a significant economic, political, and cultural activity. The knowledge economy is its economic counterpart whereby wealth is created through the economic exploitation of understanding. People that have the means to partake in this form of society are sometimes called digital citizens. As Beniger^[1] shows, this is one of many dozen labels that have been identified to suggest that we are entering a new phase of society.

What is Information?

      According to Russell Ackoff, a systems theorist and professor of organizational change, the content of the human mind can be classified into five categories:

1. Data: symbols
2. Information: data that are processed to be useful; provides answers to "who", "what", "where", and "when" questions
3. Knowledge: application of data and information; answers "how" questions
4. Understanding: appreciation of "why"
5. Wisdom: evaluated understanding

Data... data is defined as recorded facts and figures.
Information... information is knowledge derived from data.

Knowledge... knowledge is data which an individual recognizes as relevant ans is thought is aboutm interpreted, stored or used for a purpose

Understanding... understanding is an interpolative and probabilistic process. It is cognitive and analytical. It is the process by which I can take knowledge and synthesize new knowledge from the previously held knowledge. The difference between understanding and knowledge is the difference between "learning" and "memorizing".

Wisdom... wisdom is an extrapolative and non-deterministic, non-probabilistic process. It calls upon all the previous levels of consciousness, and specifically upon special types of human programming (moral, ethical codes, etc.).

Good and Poor Information

Good and Poor Information

There is a tremendous amount of useful, factual information available online. Unfortunately, it's also very easy to find incorrect or misleading information when searching online.
It can be quite difficult to determine whether the information you find on the internet is good or bad. Lots of incoherent information is posted every day by people simply looking to jump ahead in the search engine rankings.

Have you ever read through an entire article or website, only to realize that you have more questions than you did when you started? You've probably stumbled upon some poor information in your time using the internet. There are different kinds of incorrect information available online; read on to find a description of these different types.

Intentionally Misleading Information - If you've browsed Wikipedia for a fair amount of time you've probably came across a page that was locked. This happens often when celebrities are are involved in scandals or when they pass away. Some of the comments you may encounter are totally inaccurate, while others might be controversial and subject to argument on both sides of the issue.

Wikipedia's administrators lock pages when there are too many edits coming in that present false information. This is especially common for the pages of celebrities with poor reputations, which often have derogatory information posted on them. Visit the page of a controversial celebrity and look at the edit history; you'll almost definitely see some of these edits. This is one of the negatives that come with user contributed sites, and these things must be screened carefully when the open source frameworks permit such easy access by the general public.

Unintentionally False Information - Everywhere you look online, you'll find someone claiming to be an expert and sharing his or her secrets. While they may not be trying to intentionally mislead you, they're often not 100% correct.

Always question the claims of any self-proclaimed experts online. You can double-check the facts behind their statements to be sure that what they're saying is truthful. Most of these people are simply trying to make money, and even though they may not have any malicious intent, the end result still has you believing false information.

Despite all of this, don't be scared to find information online. There's still a huge amount of useful information that can be found on the internet; you just have to do a little extra research sometimes and try to stick to reputable sources. Stick with these sources and more likely than not, you won't be mislead.

Information source

 

       "Source" means the origin of something. An information source is a source of information for somebody, i.e. anything that might inform a person about something or provide knowledge to somebody. Information sources may be observations, people, speeches, documents, pictures, organizations etc. They may be primary sources, secondary sources, tertiary sources and so on.


      Primary Sources

      Academic research is based on primary sources: original 'material' from the field one is studying, including books, articles and letters written by the people or in the field one is studying, interviews with persons involved in the field, speeches and lectures which they delivered, diaries they kept, etc. Scholars consult primary sources in search of new material and/or insights that have not previously been reported by other scholars, or have been reported differently or perhaps even 'mis-reported' by other scholars.

       Secondary Sources

      Secondary sources are accounts of events which were created well after the event occurred. Secondary sources are based on primary sources — they are usually studies which analyze, evaluate, interpret, or criticize primary sources. By assessing, repackaging and distributing information, secondary sources make the information more accessible.

       Tertiary Sources

In addition to primary and secondary sources, there are also tertiary sources. These are sources that compile or digest other sources. Some reference materials and textbooks are considered tertiary sources when their chief purpose is to list, summarize or simply repackage ideas or other information. Tertiary sources include dictionaries and encyclopedias, Wikipedia and similar user-contributed online 'encyclopedias' and reference material, as well as various digests (including the Reader's Digest and similar) and schoolbooks.

Generally, tertiary sources are not considered to be acceptable material on which to base academic research. However, this depends on the topic being covered and the reason the source is used. If a language scholar is comparing different definitions of terms in a selection of contemporary dictionaries, or describing different shades of meaning of the translation into Finnish of a term from English on the basis of available dictionaries, the use of these dictionaries as sources would not only be entirely appropriate and essential to the research, but also take on the status of primary sources.
