A portal or gateway site is the best place to begin research. These sites, which are intended to serve as "jumping off" points, will lead the researcher to a variety of useful sources that have been selected because of their relevance or quality. A portal site may include thousands of links on a wide range of topics, or may be very specific in scope and point to a small number of resources.
Portal sites may allow keyword searching, provide topical, hierarchical browsing (drilling down) or both search and browse capabilities. Another useful starting point for research is the search engine, particularly those that are subject-specific.
