Finding the EvidenceSlide3

e-books (electronic books) via Discover

http://libguides.liv.ac.uk/onlineprogrammes

Further e-book search options/ individual collections:http://libguides.liv.ac.uk/onlineprogrammes/ebooks Search, Browse, Print & downloadRegister for a profile within e-book databases/ search platforms such as Discover for...Save items to your bookshelfHighlight and make notes on the book, see our guide on using a personal profile in Discover. E - booksSlide4

Electronic journals or e-journalsAccessed via Discover or other major multi-source databases or individual collections/ platforms

http://libguides.liv.ac.uk/onlineprogrammes/ejournals

Read online or print / download articles Browse or search issuesTo find articles on specific criteria visit the homepage of platforms/collections to see advanced search options (e.g. Discover Advanced Search Options):E - journalsSlide5

An electronic index to journal articles, conference proceedings and papers, reports, government and legal publications, patents, books

Contains citations, abstracts and often links to the full text

Library has many different databases but they all work with the same conceptsWhat is a DatabaseSlide6

Clear questionAppropriate keywords

Select keywords from question

A databases will retrieve exactly the words you type Use ‘operators’ to link keywords togetherSynonyms or similar termsList similar terms or alternative spellings (pediatric OR paediatric, obese OR overweight )Construct your search strategy with these points in mindBefore you start!Slide7

Question

exercise

“Weight

Loss”

What are the key concepts?

Now you have your key concepts what do you do with them to help answer your question?

“high blood

pressure”

Does weight loss and exercise help reduce

high blood pressure?Slide8

To retrieve relevant information you need to be able to

link concepts/keywords

togetherDatabases use Boolean operators to do this There are three main operators: (broadens search) OR will show more results (narrows search) combines concepts (excludes a concept) use with CAUTION Keywords and Boolean operators

OR

AND

NOTSlide9

Truncation – alcoho

*

..will show:alcoholicalcoholalcoholismalcoholicsProximity SearchingDatabase dependant See LibGuides – Guides for boolean help sheet TruncationSlide10

Phrase searchingInverted commas around a phrase or termHeart disease will search for heart, disease, heart disease

“

heart disease” will search for heart diseaseLimitsApplying limits will focus your searchPublication date, age, publication types, peer-reviewed article, systematic reviews etcRemember limits are database dependantPhrases & LimitsSlide11

Scopus is the world’s largest abstract and citation database of peer-reviewed literature and quality web sourcesContains 45.5 million records, 70% with abstracts

Nearly 19,500 titles from 5,000 publishers worldwide

70% of content is pulled from international sourcesIncludes over 4.6 million conference papersScopusSlide12

Phrases need to be in “quotation marks”Think of alternative terms for your topic – obese

overweight

obesityTry proximity operators –useful for some searchesSearch terms separately and combine similar terms with OR Use AND to combine these ‘groups’ of similar termsUse limits to reduce the number of resultsScopus - tipsSlide13

From the main Library Web pages (http://liv.ac.uk) and the Electronic Library

From the Library for Online Programmes (left menu “Quick Search”) or E-Resources page):

http://libguides.liv.ac.uk/onlineprogrammes Go direct to SCOPUS at http://ezproxy.liv.ac.uk/login?url=http://www.scopus.comHow to Access SCOPUSSlide14

Used to find one word near to another word in a sentence or paragraphThere may be different ways to say the same thing

“Penicillin allergy”

allergy to penicillinUsing proximity operators increases the number of results w/2 (within 2 words of each other) w/3 ( 3 words) etc “penicillin allergy” = 1,767 results penicillin w/2 allergy = 2,363 resultsProximity operatorsA phrase search for 1 would not find 2Slide15

A reminder of our question

Searching Scopus

Does weight loss and exercise help reduce high blood pressure?

“Weight

Loss”

exercise

“high blood

pressure”Slide16

MEDLINE is the premier, comprehensive biomedical database from the US National Library of Medicine Updated daily -latest bibliographic citations and author abstracts

More than 3,900 biomedical journals

Journals from more than 70 countriesAbstracts are included in more than 75% of the recordsCoverage 1948 to presentMedlineSlide20

Medline has a thesaurus – a controlled list of termsWhatever terms the author has used the indexer will try and ‘map’ the term to a term on this list

These thesaurus terms are referred to as MeSH terms or ‘

Medical Subject Headings’ or sometimes ‘subject headings’If your search terms ‘maps’ to a term in this list it will appear in your search history with a / hypertension/Exploding means including more specific terms lower down the thesaurus tree Medline - tipsSlide21

If you chose to ‘explode’ your term will appear in your search history with an exp

e.g.:

exp hypertension/ExplodingExploding - includes all terms LOWER in the thesaurus treeSlide22

Common problems:

Spalling

mistakesTyyping errorsSearching with the wrong keywords Incorrect symbols for Boolean, truncation or wildcardSearching on the wrong database Check online help or ask a librarianResults not what you expect?Slide28

Do you have a good article already? Look it up on the database and see how its indexed. Have you used these terms? Would it expand / widen your search?

Is there an author who writes on your topic? Have you searched to see what else they have written?

If you have found a good result are there similar article suggested by the database or the ‘Find it @ Liverpool’ option?Have you tried...Slide29
