A new search interface has been introduced for Web of Science, one of the databases in national access. It gives access to Web of Science – Core Collection from 1970 onwards and, under another tab, Journal Citation Report . The interface is considerably simpler than the old one, but more advanced search options can be found in various drop-down menus.
