Non-Documentary Sources

1. Introduction

Not all information comes from books, journals, or databases. Much knowledge is shared directly through people, institutions, organisations, and media without being formally recorded. These are called non-documentary sources of information. They are important because they often provide first-hand, latest, and practical knowledge that may not be published.

2. Non-Documentary Sources: Meaning

Non-documentary sources are those sources that are not formally recorded in print, written, or digital formats. Instead, they are communicated orally, visually, or interactively. In library science, non-documentary sources are human and institutional sources of information, mass media (like TV, radio), and interactive digital media (like the Internet) that provide knowledge without being preserved in permanent documents. Simply put, they are “live” information sources such as experts, organisations, or communication channels. Examples: Experts’ advice, government departments, research organisations, television news, radio broadcasts, institutional websites, online forums.

3. Importance of Non-Documentary Sources

• Latest and Timely Information: They provide real-time updates much earlier than books or journals (e.g., expert opinions, TV news, government briefings).
• Authenticity and Reliability: Information comes directly from experts, institutions, or official bodies, making it credible and trustworthy.
• Specialised and Practical Knowledge: Useful for solving specific problems in research, industry, education, and government where published data may not exist.
• Interactive Nature: Allows two-way communication—users can ask, clarify, and discuss with experts or organisations.
• Filling Information Gaps: Supplements documentary sources, especially in emerging fields or during emergencies.
• Wide Reach through Media: Radio, television, and the Internet spread knowledge quickly to large and diverse populations.
• Support for Decision-Making: Crucial for policy makers, administrators, and researchers to take informed and timely decisions.

Non-documentary sources are important because they are timely, authentic, specialised, interactive, gap-filling, widely accessible, and decision-supportive.

4. Limitations of Non-Documentary Sources

• No Permanence: Information is not recorded, so it cannot be stored or reused easily.
• Difficult to Verify: Accuracy and authenticity are hard to check without documents.
• Limited Access: Experts or institutions may not always be available when needed.
• Bias and Subjectivity: Personal opinions or media influence can distort facts.
• Cost and Technology Barriers: Remote access, communication tools, or expertise may be expensive or unavailable.

5. Non-Documentary Sources of Information

• Human Sources: These include experts, teachers, consultants, researchers, and practitioners. They provide first-hand knowledge through personal interaction, interviews, discussions, or oral guidance. For example, a scientist advising on an experiment or a lawyer giving a legal opinion.
• Institutional Sources: Institutions such as universities, libraries, museums, and research centres act as important non-documentary sources. They provide academic updates, seminars, training information, policies, and cultural knowledge. For instance, universities share information about courses and research activities.
• Government Ministries and Departments: Ministries and departments generate valuable information through policies, rules, statistical data, census reports, survey results, and official notifications. They act as authoritative sources of national and administrative information. For example, the Ministry of Health provides health statistics and reports.
• Research and Development (R&D) Organisations: These organisations conduct original investigations and generate new knowledge. They produce research results, technical reports, patents, innovations, and experimental data. For example, CSIR, DRDO, ICAR, and ISRO in India are leading R&D bodies.
• Learned Societies: Professional associations and subject-based organisations produce information through conferences, seminars, proceedings, technical standards, and expert recommendations. They create a platform for specialists to share knowledge. Examples include the Indian Library Association (ILA) and IEEE.
• Publishing Houses: Publishers not only print books but also act as information sources through trade bulletins, catalogues, author information, and publishing trends. They inform about upcoming titles and publishing developments. For example, Oxford University Press and Elsevier regularly release publishing updates.
• Archives: Archives preserve historical and official records, manuscripts, government files, and correspondence. They provide authentic records for reference and research. For instance, the National Archives of India preserves official documents of historical importance.
• Data Banks: Data banks are centralised bodies that collect and supply raw data in different fields. They provide economic indicators, scientific datasets, health information, and industrial statistics. Examples include the National Sample Survey Office (NSSO) and World Bank Data.
• Information Analysis Centres: These centres collect, analyse, and repackage information into usable forms. They produce state-of-the-art reports, reviews, summaries, and evaluation studies. For example, INIS (International Nuclear Information System) and NISCAIR process large amounts of technical data for researchers.
• Referral Centres: Referral centres guide users to appropriate sources of information. They do not provide the information directly, but help in locating it. They prepare directories, indexes, and referral notes. An example is DELNET, which allows users access to documents from other libraries.
• Institutional Websites: Websites of universities, research labs, and organisations provide digital access to reports, announcements, services, publications, and project data. For instance, IGNOU’s website gives details of its courses, study materials, and research updates.

Non-documentary sources provide unrecorded but highly valuable information through human expertise, institutional services, government data, research outputs, archives, media, and online platforms. They are crucial for obtaining timely, authentic, and specialised knowledge beyond what is available in printed or electronic documents.
