    • Don’t Miss Important References! RDF InformationLiteracy http://www.library.qmul.ac.uk/
    • Don’t Miss Important References! • When you are new to literature searching it’s easy to miss important references. • Here’s a few simple techniques to use when searching databases that should help you to find most of the references you need. RDF InformationLiteracy http://www.library.qmul.ac.uk/
    • Wildcard Characters and Truncation RDF InformationLiteracy http://www.library.qmul.ac.uk/  Use wildcards (*, ?, $) for word variations, e.g.  singular / plural, nouns / verbs, UK / US spellings  The asterisk (*) represents any group of characters, including no character  The question mark (?) represents any single character  The dollar sign ($) represents zero or one character
    • Wildcard Characters and Truncation RDF InformationLiteracy http://www.library.qmul.ac.uk/ Some Examples:
    • Phrase Searching RDF InformationLiteracy http://www.library.qmul.ac.uk/  To search for an exact phrase, enclose the phrase in quotation marks  For example, the search query "energy conservation" will retrieve all references that contain the exact phrase energy conservation
    • Boolean Operators RDF InformationLiteracy http://www.library.qmul.ac.uk/ Use Boolean operators to combine your search terms (e.g. AND, OR, NOT, NEAR, etc)
    • Boolean Operators RDF InformationLiteracy http://www.library.qmul.ac.uk/
    • Controlled Vocabulary RDF InformationLiteracy http://www.library.qmul.ac.uk/ Find any controlled vocabulary available for the subject area you are researching People who index information for a database will use controlled vocabulary from a list of keywords, often listed online, to: • Provide a consistent method of finding information that uses different terms for the same concepts • Find information on a broader or narrower aspect of a particular subject
    • Controlled Vocabulary RDF InformationLiteracy http://www.library.qmul.ac.uk/ • There are two main kinds of controlled vocabulary tools used in databases: subject headings and thesaurus terms
    • Controlled Vocabulary RDF InformationLiteracy http://www.library.qmul.ac.uk/ Subject Headings • Describe the main focus of the content of a publication • Provide terms which bring together different ways of defining a subject e.g. MESH subject headings from the PubMed database
    • Controlled Vocabulary RDF InformationLiteracy http://www.library.qmul.ac.uk/ Thesaurus Terms • Thesauri list words grouped together according to similarity of meaning • Thesauri list not only equivalent terms but also narrower, broader terms and related terms e.g. Thesaurus terms from the Compendex database
    • Conclusion RDF InformationLiteracy http://www.library.qmul.ac.uk/ In order to avoid missing important references, use these search techniques – either singly, or by combining them in a search: • Wildcard characters and truncation • Phrase searching • Boolean search operators • Controlled vocabulary (subject headings and thesaurus terms)
