This session
How to do subject searches for journal articles, conference papers, book chapters etc
How to cite electronic sources correctlyHow to avoid plagiarism
Subject searching
SOLO, OLIS and Oxford e-journals cover Oxford holdings only
Better to use specialist indexes covering the world’s literature
Access via OxLIP+Use inter-library loan for items not held
in Oxford and not online
Major sources
Today we cover:Web of KnowledgeSCOPUSGeoRefGoogle ScholarMany others available: see OxLIP+
Going home
These are mostly subscription databases
Only available on Oxford networkOutside Oxford, login using your SSO –
Single Sign On – username and password (as for Webauth / Herald e-mail)
Athens/VPN no longer needed
What can you find on Oxlip+?
Library catalogues including OLISBibliographic databases (journal article
summaries & tables of contents)Full-text electronic journalsInternet sites (subject gateways)Reference works & Statistics
Glossary
Bibliographic Database= an indexed source of citations of journal articles
(Use these to search for content, e.g. book chapters and journal
articles)
Library Catalogue= a list of books, journals, maps, records, etc. held in the library and arranged in a systematic manner(Use this to search for a book or journal, once you know the title of the journal or the author or title of a book)
Bibliographic databases Excellent for locating journal articles, book
chapters and book reviews (NB. References only, NOT necessarily [though increasingly] full text)
General or Subject specific coverageDifferent interfaces but similar functionalityNot tied to library holdingsSome will provide a link to full text
Bib. databases - Interdisciplinary
Web of Knowledge (http://wok.mimas.ac.uk)
Web of Science covers journals in all subject areas
Citation searchingScopus (http://www.scopus.com/scopus)
Provides an alternative to WOK for cross-disciplinary search and citation searching; incorporates Geobase
Relevant Subject Databases
GeoRef (for geology)Biological Abstracts (life sciences and
environment)CAB Abstracts (environment)These are available on OvidSP Gateway
software and can be cross-searched there
Search strategy
Ask a clear search questionWhat is the impact of tropical deforestation on our climate?
Break the question into search conceptstropical deforestation, climate change
Combine terms into a search strategy using Boolean connectors
Find more terms from retrieved records whilst you are searching
Boolean connectors:
AND, OR, NOT
AND to narrow the searchOR to broaden the search (synonyms)NOT excludes search terms
OR, AND, NOT
Tropical deforestation
Climate changeEnvironment
Other tricks:
Use symbols for wildcards and truncation? for a single character
wom?n will find woman or women
* for truncation or variant spellingsenzym* for enzyme, enzymes, enzymology etc
use quotation marks for searching for phrasese.g. “non-ferrous metals”
Sample search
What is the impact of tropical deforestation on our climate?
AND = narrows OR = widensSearch string could be:“Climate change” and “tropical
deforestation”
Getting your hands on the full- text Is there a link to full text from the database? Is the journal available electronically in Oxford?
Check Oxford e-Journals (http://journals.ouls.ox.ac.uk)
Is there a print copy in an Oxford library? Check SOLO (http://solo.ouls.ox.ac.uk/olis/)
If not, try Inter-Library Loan from the Earth Sciences Library or RSL Default means of delivery is SED = Secure Electronic
Delivery
Databases vs. Search engines
Contents are indexed by subject specialists
Subject headings Limiting functions e.g.
publication types, languageAllow you to View Search history Combine searches Mark and sort results Print/save/email/export Save searches Set up alerts
Searches done by automated “web crawlers”
No thesaurus / subject headings – just free text searching
No limiting functions
Usually none of these!
Google Scholar
Has links to many, but not all, journal publishers
So not all journals can be found through GS
Records can only be selected singlyBut quick route to full text when
relevant article found
Citing your references
An article in an online journal which also exists in print can be cited in the same way as print
To cite something which only exists electronically, e.g. a web site, follow special rules which include the date viewed
Avoid plagiarism
Easy to copy and paste paragraphs and make it look like your own work
Heavy penalties if caught!Make sure you always give correct
citationSee:
http://www.jiscpas.ac.uk/referencing.php[or Google ‘plagiarism uk’]
http://www.jiscpas.ac.uk/referencingcitations.php
Keeping track of your referencesMake sure you keep a systematic listing of
your references, so you can find them again when you need them
A simple listing in Word should be fine, but if you have a large number of references, software like RefWorks (free) or EndNote (£80 from OUCS) can be very helpful.
Some databases allow you to export references directly to RefWorks or EndNote.
Maps
If you need to do much mapping, consider using the MapInfo software. The Bodleian Map Room staff can give you guidance.
