INFORMATION RESOURCES:

Information resources are of two kinds, namely, Documentary and Non-Documentary Sources.

Documentary Sources:

A document embodies thought. It is a record of work on paper or other material for easy physical handling, transportation across space, and preservation through time. It may be said that the thought content  of a document represents the information it contains. A document may be a macro-document  like a book, monograph, thesis, dissertation, report, etc.,  or a  micro-document  like an article in a periodical. Documents  have also been grouped as  Conventional, Non-Conventional, Neo-Conventional, Meta documents,etc. As a matter of fact, these documents are available in various physical forms such as books, periodicals and also as audio-visuals. Details of each type are given in the succeeding sections and sub-sections.

Non-Documentary Sources: 

On the other hand, non-documentary sources include: 

•  Institutional Sources 

•  Human Sources 

•  Colleagues 

•  Peers 

•  Information Gatekeepers 

•  Guides, Advisors, Consultants 

•  Vendors, Contractors, Collaborators, etc.
