Human behaviour normally depends on the environment of the incident and the time of its occurrence. The behaviour of people depends on many factors and these behaviour traits are an important aspect in the Library and Information Science (LIS) field. Hence in this paper an attempt has been made to examine the behaviour traits of LIS students in South India. Out of 400 questionnaires distributed 367 have responded and the response rate is 91.75%. In this survey three aspects comprising student behaviour have been analysed such as Work Environment, Natural Environment, and Social Environment. In the case of Work Environment the respondents were grouped as Workaholic, Impatience, Achievement oriented, Rash nature, and Punctuality. Further, in respect to Natural environment, the respondents are grouped as Complacent, Patience, Easygoing, and Relaxed. Last, the respondents were grouped in the Social Environment as Balancing nature, Magnanimity, Naturalistic, Assertive nature, Dependency, Lucrative, Lonely nature, and Time Based personality. Finally the authors conclude that LIS students need to possess these qualities and behaviours to work in different environments.
