– 14 500 ejournals
– Over 175 databases
– A lot of library catalogues
• Library systems - we need something more
• How to organize
• How to use
DEFINITION by Marc Carden
A common interface that allows users to
access library-owned resources and libraryaccessible resources.
DEFINITION BY ELAG
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
