This paper identifies some natural habits and patterns of children's and adolescents' information seeking and use by drawing a wide range of studies conducted with children and adolescents as study participants. The patterns reported here indicate that children's and adolescents' information seeking and use are affected by the nature of information tasks, the qualities of access tools, their cognitive ability to seek and use information, and their prior knowledge and experience about the tasks and topics given. The findings should provide insights for identifying future research issues as well as for programming the information environments particularly conducive to learning.
