One of the advantages of the Internet database is that it allows concurrent searching of all three databases back to 1992. Quick Search allows searching by subject, author or author's location. Full Search lets the searcher with a relevant citation extend the search forward in time to those papers citing the original article.
Searchers can navigate backward in time, as all cited references are included in citation entries.
Those citations within our subscription dates are hot-linked directly to the abstract. Using the Related Records button, a searcher can explore across time to identify papers that share at least one of the references cited in the original paper. ISI uses a standard web-browser interface, indexes all of the journal, uses author's abstracts, and adds KeyWords to supplement author's keywords.
