                Notes            Common Search Interface

                                 A library portal must act as an intermediary, allowing users to search different resources (with
                                 different search protocols and metadata in different formats) using a single search interface and
                                 thereby eliminating the need for the user to learn and remember the particular search characteristics
                                 of each resource.

                                 Federated Search

                                 It must also allow end users to select more than one information resource, and then to search all of the
                                 selected resources simultaneously. The user to be presented with an integrated set of search results
                                 that can ultimately be merged, sorted and perhaps exported as a single list of relevant references.

                                 Direct Access to Content

                                 It must have a context sensitive dynamic linking service integrated with a library portal to allow
                                 users to move from a document citation to the full text of the document in electronic form with the
                                 click of a mouse.
                                 Authentication

                                 A library portal must provide access to licensed or commercial resources without users having to log
                                 in to each one with different usernames and passwords.
                                 Increasing number of libraries are now looking for an automated library systems that include a portal,
                                 which serve as a single user interface to provide access to a wide variety of electronic resources both
                                 within and outside the library.
                                 According to Boss a typical portal must have the following features:
                                 Customisable Web Interface

                                 Portal must have an easy to navigate interface that can be designed to match the look and feel of an
                                 organisation’s existing applications. Portals are generally implemented with Web browsers, but it is
                                 possible to use another client interface such as a GUI.


                                 Personalised Content Presentation

                                 Portals personalised on the basis of users profile information to deliver personalised content can add
                                 value to the service. The personalisation can be for an individual or for a category of individuals.

                                 Security

                                 Most portal servers use caching to improve performance. The users access the cache, rather than the
                                 backend server that is the source of the information. User profiles can be used to increase the security
                                 of the systems being accessed. Patron authentication is another security feature required to determine
                                 rights to access. Access could be limited to specific individuals or categories of people.
                                 Communication and Collaboration

                                 Portal can also be used to provide chat, e-mail, shared calendars, Web meetings, etc. A library portal
                                 has the potential of changing how libraries are used and how librarians do their work and thereby
                                 bring real change to professional and organisational culture.
