Individuals play different roles in their lives i.e professionals, parents, citizens etc and their each role require information to fulfill his duties in a better way. Information requirement or Information need is an inner apprehension which appears in the mind of user when he feels that there are gaps in his knowledge and he has to solve any problem.
According to Wilson (1981) "Information need is a subjective experience which occurs only in the mind of the person in need and consequently is not directly accessible to an observer".
Information need depends on different factors; according to Choudhary (1999) Information needs vary from job to job and organization to organization. Crawford (1978) describes information need depends on Work activity and hierarchical position of individuals. Paisley (1968) identifies professional orientation effect on information need. Devadason and Lingam (1997) characterize nature of work as a factor of information need. All authors emphasized information need highly depends on work activity or kind of job. Some jobs are information dependent for example journalistic writing needs dependable information.
