• Compiled by people, not robots

• More focus on sifting for relevance and quality

Good For: topics that fall into a thematic area that has a subject directory, guided browsing in your subject area

Not Good For: Quickly finding information from widely varying themes

What is a portal?

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 collate this into an amalgamated form for presentation to the user. This presentation is usually via a web browser, though other means are also possible. For users, a portal is a, possibly personalised, common point of access where searching can be carried out across one or more than one resource and the amalgamated results viewed. Information may also be presented via other means, for example, alerting services and conference listings or links to e-prints and learning materials.
