Electronic Resources Electronic Resources represent an increasingly important component of the collection-building activities of libraries. “Electronic resources” refer to those materials that require computer access, whether through a personal computer, mainframe, or handheld mobile device. They may either be accessed remotely via the Internet or locally. Some of the most frequently encountered types are: · E-journals · E-books · Full-text (aggregated) databases · Indexing and abstracting databases · Reference databases (biographies, dictionaries, directories, encyclopaedias, etc.) · Numeric and statistical databases · E-images · E-audio/visual resources (IFLA Guide,2012) August 20, 2012 5

  43. 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. August 20, 2012 43
