Introduction

A “source” is anything that provides you with information. There are mainly two types of
information sources. They are: documentary and non-documentary. The documents are physical
sources of information that are fit for physical handling or they are the record in some physical
form. The non-documentary sources of information are live sources that provide information
instantly. The non-documentary sources of information include research organizations, societies,
industries, government establishment, departments, learned and professional bodies, universities,
technological institutions, etc.
