Key Skills – Library Research • “Able to research appropriate periodicals, websites, books and other references to draw together the required information”
The Library’s Electronic Resources • Almost all of the Library’s electronic resources can be accessed from off site via the Library web pages • For electronic journals start from the Library OPAC • If prompted for a password use your ITS login rather than an ATHENS password unless other instructions are given
ConneXions • Introduced during Summer 2004 • Develops links between Library OPAC and bibliographic databases • Provides links from many of these databases to full text (where available)
Types of Material • Periodicals – printed and electronic • Abstracts and Indexes (Bibliographic Databases) • Websites • Google - try the Advanced Search screen ∞ • Google Scholar (under development) ∞ • Vivisimo (http://vivisimo.com) ∞ • Gateways • Books • Abstracts and Indexes (Bibliographic Databases) • Library catalogues ∞ • Newspapers • Data Sources • “Grey literature”
Databases (v. Internet) • Peer-reviewed Material • Restricted access • Covers print as well as electronic (usually) • More sophisticated searching
Internet (v. Databases) • Generally, not evaluated • Electronic/digitised • Large number of items but some “quality” material not included • Difficult to assess results of searches
Understanding Databases • Subject Scope • Inclusivity • Number of sources • Type of material • Level of material • Date range • Geographical bias
Understanding Databases • Search defaults • Features provided • Abstracts? • Option to create subsets? • Printing/Saving/E-mailing? • Links to full text? • Links to local catalogue? • Remember to use the help screens
Databases: Getting Started • Library home page • http://www.dur.ac.uk/library/∞ • click on Databases • or use Subject Information pages for Economics or Business ∞
Database Searching • Keyword • Hierarchical Structure • Coded Concepts
Keyword • Random • matches patterns not concepts • Scope • Title only • Abstract • Full text • Syntax • Semantics • Ambiguities • Alternatives • Language problems
Keyword • Truncation (Stemming) • Aggress* • Word combination • Usually Boolean
Boolean Searching • Syntax • Similar to formula in Mathematics • BUT symbols not used as consistently • BUT “default” values vary between databases
Boolean Searching • AND • OR • Either and Both • NOT • To be used only with care
Word Combination Defaults Interest Rate* may be searched as Interest and rate* (e.g. Library OPAC) Interest or rate* (e.g. some search engines) Interest rate* (e.g. Web of Science)
Adjacency and Proximity • Adjacency • Phrase searching • Words next to each other • “same” and “sent” • Proximity • Words within a given distance • Silence w3 lambs
Semantics • Ambiguities • Alternatives • The whole and parts • Public sector employees • Excluding meanings • Language problems • Romans; Email

Refining Searches • Truncation (stemming) • Econom* • Wildcard • Economic behavi*r • Wildcard and truncation • Econom* and Tan?an* (Examples from Web of Science)
Citation Searching SCHULTZ, T.: Declining economic importance of agricultural land. Econ. j. 61,1951,725-740 • Pre-dates Web of Science • BUT Web of Science can be used to trace subsequent references to it and thus find more recent research on the same topic
Hierarchical Structure Economics Financial Economics Taxes and Taxation Consumer taxes V.A.T.
Coded Concepts • Usually a notation for a hierarchical structure • Arrangement of books in a Library • Application to databases (e.g. EconLit)
Internet Gateways/Portals • Selected Unrestricted Electronic Resources • Often classified • May be evaluated/annotated • SOSIG (http://sosig.ac.uk) ∞ • See also other links from Subject Information pages ∞
Newspapers • May include current debate on some possible project topics • Electronic archives for some available from Library’s “News, weather…” page ∞ • Infotrac: Custom Newspapers provides multiple title searching ∞
Newspapers • Lexis-Nexis ∞ • “Executive” is a prime source for Financial and business news • “Executive” can also be used for major overseas newspapers • “Professional” is useful for UK regional newspapers
Data Sources • A selection is available from the Subject Information pages for Economics ∞and for Business ∞ • ESDS ∞ is increasing its coverage of major international datasets • Simple individual registration needed (use ITS login) • Work through an access guide before using the service
“Grey Literature” • Working Papers • Sometimes available free via EconPapers ∞ or IDEAS ∞ • Official Publications • International bodies • NGOs • Governments • Often free on web site of organization
