This paper explores the relationship between community informatics and library and information science. Community informatics is broadly defined as the use and application of information and communication technologies (ICTs) in local communities. I examine why there is a growing interest in communities, discuss what is community informatics, and examine the relationships between community informatics, community networking and library and information science (LIS). I demonstrate how the LIS perspective can inform community informatics, and highlight issues of shared interest between community informatics and library and information science. Finally, I draw attention to potential areas for collaboration between community informatics and library and information science, and consider the connection with libraries and library users.
