Subject Gateways : An Overview

摘要

In the traditional information environment human intermediaries, such as publishers and librarians, filter and process information so that users can search catalogues and indexes of organized knowledge as opposed to raw data and disparate information. Subject Gateways offer the user an alternative to the generalized approach of search engines. Search engines in a sense perform the job of public libraries on the Internet, while the subject gateways are special libraries, and also support teaching and research on their respective subjects.
