This week
Databases– basic search strategies– advanced search techniques– marking and exporting references– finding full text– saved searches and alerts
![Page 5: Library Resources Barbara Dorward November 2012. Previous session Catalogues Library resources Finding information on the web Evaluation of information.](https://reader030.fdocuments.us/reader030/viewer/2022032604/56649e595503460f94b52b4d/html5/thumbnails/5.jpg)
Why databases?
Because they
link to up to date information from peer reviewed publications
are usually well indexed enabling you to search in detail
contain abstracts summarising the articles retrieved
often link directly to the full text if it is available electronically
![Page 6: Library Resources Barbara Dorward November 2012. Previous session Catalogues Library resources Finding information on the web Evaluation of information.](https://reader030.fdocuments.us/reader030/viewer/2022032604/56649e595503460f94b52b4d/html5/thumbnails/6.jpg)
Which databases..?
The most important ones for ORC are
INSPEC (Physics Abstracts)
Compendex (Engineering Index)
Web of Science (Science Citation Index)
All are nationally or internationally produced so there is no guarantee the library will have all the relevant articles you find

Searching the databases by topic
Search statements retrieve exact matches
Use Boolean operators (and,or,not) to combine search terms
Use truncation,stemming and wild cards (symbols vary between databases)
Enclose exact phrases in quotation marks (usually) e.g. ‘black holes’

Searching by author
Useful for key authors in a field
Follow database instructions for input format
For common names, limit by address or topic

Controlled (Thesaurus) terms
Terms added to a record taken from a fixed list (thesaurus)
Searching these makes results more relevant by– avoiding concepts mentioned in
passing– retrieving material containing
alternative terms
