DEFINITION by Marc Carden

A common interface that allows users toaccess library-owned resources and library-

accessible resources.

A LIBRARY portal is an application which allows one-stop-shop access/searching and discovery via a unified single-point interface to organized heterogeneous resources and enabling services to a pre-defined community (users)

DEFINITION BY JISC

• Technically, a portal is a network service that brings together content from diverse distributed resources using technologies such as cross searching, harvesting, and alerting, and collates this into an aggregated form for presentation to the user, usually via a website
