Library and Information Science: Chapter One and Two Study Notes

CHAPTER ONE

The term information originates from the Latin word informare (in + formare), meaning 'to inform somebody of or about something'.
Defining information can be complex as it has multiple dimensions, interpreted differently by individuals.
Information is often synonymous with news, facts, data, and knowledge (Aina, 2004).

Data: Raw, unprocessed facts.
Information: Processed data that generates meaning and is communicated.
Knowledge: Further processed information that is organized and widely understood and applied.
Wisdom: Knowledge applied for societal benefit.
This relationship can be visually represented as:
ext{Data}
ightarrow ext{Information}
ightarrow ext{Knowledge}
ightarrow ext{Wisdom}
Information fulfills curiosity and personal goals, impacting both individuals and national development (Nwosu and Ogbomo, 2010).

An information society is characterized by:
- Dominance of the creation, distribution, and manipulation of information as key economic and cultural activities.
- High information intensity in daily lives, workplaces, and technological competencies enabling data exchange.
It is commonly referred to as the information age and is founded on the principle that "information is power"; success often hinges on access to information.

Information is crucial in various sectors, including:
- Development: Acts as a foundation for development processes.
- Uncertainty Resolution: Reduces ambiguity by offering potential solutions.
- Promotion of Knowledge: Enhances educational experiences, leading to personal transformation and societal improvement.
- Governance: Facilitates accountability and empowerment.
Information is particularly essential during democratic processes for citizen enlightenment.

Primary Sources: Firsthand accounts including original research results, raw data, testimonies, speeches, and historic objects. Examples:
- Original research articles
- Eyewitness accounts
Secondary Sources: Analyze and interpret primary sources; not direct evidence but provide commentary. Examples:
- Articles synthesizing original research
- Critiques of creative works
Tertiary Sources: Overviews or summaries of topics, providing context. Examples:
- Textbooks
- Encyclopedias
- Dictionaries

A library is a system for systematically collecting, organizing, storing, preserving, and disseminating information materials. Resources range from:
- Print: Books, periodicals, government publications.
- Non-Print: Digital formats like CD-ROMs, databases, internet resources.
The term library derives from Latin liber, meaning book.
Definitions:
- Dictionary of Library and Information Science: "Library is a collection or group of books and/or other materials organized for use."
- British Dictionary: "A room or set of rooms where books and other literary materials are kept."

Ancient Era: Libraries began with the history of the written record and transitioned from oral traditions to written forms of preservation. Early libraries emerged in ancient civilizations (Egypt, Greece, Rome).
Middle Era: Christianity fostered book collections in monasteries focusing on doctrine and lettered works.
Modern Era: The 20th and 21st centuries see the predominance of electronic formats in information storage and access.

Information Dissemination: Providing diverse information formats to clients, enabling access to relevant information.
Unifying Role: Serving as a conduit for cultural transmission.
Research Support: Aiding the creation of new knowledge via resource acquisition.
Recreation: Facilitating leisure through various media.
Independent Learning: Supporting self-directed study beyond institutional confines.
Economic Role: Offering access to learning materials for economically disadvantaged individuals.

Academic Libraries: Serve educational objectives of higher institutions, aimed at supporting teaching, learning, and research.
- Functions include providing print/non-print materials, resources for term papers, and recreational materials.
- Example: University Libraries, which provide resources relevant to diverse disciplines and aid the institution's educational mission.
School Libraries: Located in primary and secondary schools, aiding educational support and promoting reading habits.
National Libraries: Apex libraries collecting and preserving a nation's published materials, serving as knowledge databanks. Notables examples include The Library of Congress (USA), British Library (UK), Bibliothèque Nationale (France).
Public Libraries: Funded by taxpayers, offering resources to the general public irrespective of their backgrounds, and often serving marginalized groups via mobile services.
Special Libraries: Serve specific organizations by providing tailored resources relevant to their operations. Examples include corporate libraries serving industries.
Private Libraries: Owned by individuals or families, often focusing on personal interests or research areas. Examples include notable private collections donated to institutions.
Virtual Libraries: Existing without a physical space, providing online access to library resources, enhancing convenience and accessibility.

Libraries fulfill various functions, including resource acquisition, information dissemination, cultural preservation, research support, recreation facilitation, and independent learning assistance.
The unique characteristics of each library type emphasize their specific roles within their communities and sectors.
