An Introduction of
Library Portals

In the process of

 Information Retrieval System


*      Introduction

There are as many types of websites as there are types of human activity. As the size of a website grows so does the need for better searchability and browsability. As the size of a website grows even more and as the intended audience of the website’s content becomes more diversified, so does the need for user-driven customization and personalization.

The terms ‘portal’ tend to be used interchangeably and often in combination to indicate a service providing browser-based access to information resources and applications. In data networking a portal is a device that translates a data stream from one protocol to another, without adding any additional value in the conversion  process. The notion of a portal is something more than a simple switch or exchange, and usually provides a higher level of combination and personalization.

Many library websites grew quickly as new sources of digital information .

In order to customizing and Integrating the access point; the portals emerged assisting to the process of retrievaling information and data.

*      Some Differences Between Website And Portal.

The Portal and website can be differentiated as :

A portal is generally a vehicle or medium by which to gain access to a huge number of 'services'. A web site is a destination in itself.

In Other Words;

Web is like a city. Portal is like a gate. One can enter the city via a gate and  wonder around wherever one wishes and can exit from any gate he wishes.

So;

A website is a destination in its own right. It is an end point for the visitor. The creators have built the site to keep you there. A portal on the other hand is not a destination as such. Rather it is more like a bus terminus, signposting users onwards to other places.
