ETH-BIBLIOTHEK: ACCESS TO DATABASES • Searching the Knowledge Portal / the NEBIS rechercheby database title • Access by subject • Access by alphabetical list
SFX FUNCTIONALITY • Context-sensitive service, enabling you to accessthe document you require (possible from almost all DBs) • Link to the full text • Link to the library catalogue • Link to the table of contents of a journal • Link to an interlibrary loan service (ILL)
SEARCH STRATEGIES • Formulate the search query (type of information, topic) • Subject: general overview ↔ selectedinformation? • Initial (term) search in Wikipedia, encyclopaedias, including reference works • Advanced search in subject databases • Synonyms, truncation, links, phrase search, alternative spellings, singular/plural forms, time coverage, etc. • The more precise the query, the more accurate the hits but, equally, the more often documents fall through the net • Document and save your search history!
SEARCH RULES I: BOOLEAN OPERATORS, PHRASE SEARCH • AND Switzerland AND tourism - both terms must occur in the document (intersection) • OR bicycle OR bike - at least one of the terms must occur in the document (union) • NOT Asia NOT India - the document contains the first term but excludes the second (subset) • SAME Clinton SAME Obama - both terms must occur within the same sentence • NEAR climate NEAR/3 change – between both terms are zero to three other words • ( ) Search order precedence: operators are weighted differently depending on the database, e.g. AND > OR > NOT – or the other way round! • This weighting can be changed using brackets. Tip: Consult the Help pages! • " " "hybrid car" - keeps terms together, or searches for them in the document in that exact order (phrase search)
SEARCH RULES II: TRUNCATION / WILDCARDS Tipp: Consult the Help pages! - often there is a context-specific Help function available (OVID SP, Web of Science, Scopus)
