In the 21st century, the internet has become a powerful, popular and more essential channel for the delivery of reference services and it is rapidly gaining wide patronage. In order to key into this new concept, libraries have resorted to leveraging digital technologies to meet the information needs and demands of the 21st century seekers in this era. However, to freely and confidently utilise the digital technologies in reference service delivery, there is a need to have policies which will guide the reference service delivery and the technologies to adopt. This paper discussed the library policies for 21st century reference service delivery and its implication for present day information seekers that will enhance reference services. It also explained the five laws of library science as applicable to reference services in this period, the information sources required and the way forward.
