Session Outline <ul><li>Why do literature searches </li></ul><ul><li>Finding books – a quick recap </li></ul><ul><li>What are journal articles </li></ul><ul><li>Finding journal articles </li></ul><ul><li>Improving your internet searching </li></ul><ul><li>Information Sources Quiz </li></ul>
    3. 3. Information Sources <ul><li>Lecture Notes </li></ul><ul><ul><li>Good starting point for assignments. </li></ul></ul><ul><li>Books </li></ul><ul><ul><li>Good sources of background information. </li></ul></ul><ul><li>Journal Articles </li></ul><ul><ul><li>Good source of information on latest research </li></ul></ul><ul><ul><li>Provide more detailed information than books </li></ul></ul><ul><li>Geological Surveys </li></ul><ul><ul><li>For geological data on a particular area. </li></ul></ul><ul><li>Websites </li></ul><ul><ul><li>Can provide useful information </li></ul></ul><ul><ul><li>Need to evaluate website before using </li></ul></ul>
    4. 4. Literature Searches – why do them? <ul><li>“ A few months in the laboratory can save a few hours in the library.” - Westheimer's Law </li></ul><ul><li>You need to know what research has already been done so you can build on that research </li></ul>
    5. 5. Finding Books – A Quick Recap <ul><li>Library catalogue: http:// </li></ul><ul><li>Brumbaugh, D. S. 1999. Earthquakes: science and society. Prentice Hall. </li></ul><ul><ul><li>Use the ______________________ search </li></ul></ul><ul><li>Books by Philip Kearey </li></ul><ul><ul><li>Use the ______________________ search </li></ul></ul><ul><li>Books on volcanoes </li></ul><ul><li>- Use the ___________________ search </li></ul>Author/Title Author Word or Phrase
    6. 6. Why Use Journal Articles? <ul><li>Journals </li></ul><ul><ul><li>Publications that are issued at regular intervals </li></ul></ul><ul><ul><li>Also called serials or periodicals </li></ul></ul><ul><ul><li>Primary information sources through which research is made known to the geological community </li></ul></ul><ul><li>Often the most up to date reliable resource </li></ul><ul><ul><li>Quality (scholarly) journals are refereed/peer-reviewed </li></ul></ul><ul><ul><li>Articles are reviewed by other authors in the field </li></ul></ul><ul><ul><li>Comments, corrections and revisions are made to submitted papers </li></ul></ul><ul><ul><li>Final published versions are therefore quality assured by the research community </li></ul></ul>
    7. 7. Three Types of Science Journal <ul><ul><li>General journals </li></ul></ul><ul><ul><ul><li>Devoted to news, opinion, comment and articles for non-experts </li></ul></ul></ul><ul><ul><ul><li>e.g. Geology Today </li></ul></ul></ul><ul><ul><li>Scholarly journals </li></ul></ul><ul><ul><ul><li>Devoted to original research contributions </li></ul></ul></ul><ul><ul><ul><li>e.g. Journal of Geology </li></ul></ul></ul><ul><ul><li>Review journals </li></ul></ul><ul><ul><ul><li>Devoted to original contributions taking an overview of the published literature </li></ul></ul></ul><ul><ul><ul><li>e.g. Trends in Ecology and Evolution </li></ul></ul></ul>
    8. 8. Recognising Journal Articles <ul><li>Bohaty, Steven M., Zachos, James C, 2003. Significant Southern Ocean warming event in the late middle Eocene. Geology , 31 (11):1017-1020. </li></ul><ul><li>Look for whether it has </li></ul><ul><li>An ____________ & a _____________ </li></ul><ul><li>A ______________ & an ___________ </li></ul>Article Title Journal Title Volume Number Issue Number
    9. 9. What is a Bibliographic Database? <ul><li>Need to search bibliographic databases </li></ul><ul><ul><li>Effectively an online way of searching for journal articles </li></ul></ul><ul><li>Each one indexes lists of bibliographic information for publications </li></ul><ul><ul><li>Such as books and journal articles </li></ul></ul><ul><ul><li>Some overlap in coverage </li></ul></ul><ul><li>Bibliographic information normally comprises: </li></ul><ul><ul><li>Author, title, source (journal title), year, volume, page numbers & abstract summary </li></ul></ul>
    10. 10. Key Bibliographic Databases <ul><li>GeoRefs </li></ul><ul><ul><li>Geology and Earth-Sciences coverage </li></ul></ul><ul><ul><li>Includes journals most other resources don’t </li></ul></ul><ul><ul><li>http:// / </li></ul></ul><ul><li>Scopus </li></ul><ul><ul><li>General Science coverage </li></ul></ul><ul><ul><li> </li></ul></ul><ul><li>Web of Knowledge </li></ul><ul><ul><li>Multidisciplinary coverage </li></ul></ul><ul><ul><li>http:// </li></ul></ul>
    11. 11. Types of Search <ul><li>Keyword/Subject Search </li></ul><ul><ul><li>When you are looking for material on a particular subject </li></ul></ul><ul><ul><li>Need to be systematic in your searches </li></ul></ul><ul><ul><li>Ensures accurate results and avoid information-overload </li></ul></ul><ul><li>Author Search </li></ul><ul><ul><li>When you are looking for material published by key names in a field </li></ul></ul><ul><ul><ul><li>Identified in lectures, books, review journal or other articles </li></ul></ul></ul>
    12. 12. Keyword Searching (1): Concepts <ul><li>Question: Find out about ore deposits in the UK </li></ul><ul><ul><li>Identify the important concepts and words in the question: </li></ul></ul><ul><ul><ul><li>Ore </li></ul></ul></ul><ul><ul><ul><li>Deposits </li></ul></ul></ul><ul><ul><ul><li>UK </li></ul></ul></ul>
    13. 13. Keyword Searching (2): Variants <ul><li>Think about variations of the keywords you’re using: </li></ul><ul><li>Ore </li></ul><ul><ul><li>Ores, Orebody, Mineral, Minerals… </li></ul></ul><ul><li>Deposits </li></ul><ul><ul><li>Deposit, Deposition… </li></ul></ul><ul><li>UK </li></ul><ul><ul><li>United Kingdom, Britain, England, Wales, Scotland, British Isles… </li></ul></ul>
    14. 14. Keyword Searching (3): Truncation <ul><li>Saves typing! </li></ul><ul><li>Picks up multiple terms from foreshortened word-stem </li></ul>
    15. 15. Keyword Searching (4): Boolean Logic <ul><li>AND </li></ul><ul><ul><li>This is used to combine search terms to narrow your search </li></ul></ul>
    16. 16. Keyword Searching (4): Boolean Logic <ul><li>OR </li></ul><ul><ul><li>This is used where various terms might describe the same object </li></ul></ul>
    17. 17. Keyword Searching (4): Boolean Logic <ul><li>NOT </li></ul><ul><ul><li>This is used when you wish to exclude a word from your search </li></ul></ul>
    18. 18. Keyword Searching (5): Search Strategies <ul><li>Brackets are used as in a mathematical equation, to tell the database how to combine the words </li></ul><ul><li>(ore* OR mineral*) AND deposit* </li></ul><ul><li>A more specific search could be: </li></ul><ul><li>((ore* OR mineral*) AND deposit* AND (uk OR united kingdom)) NOT hematite </li></ul>
    19. 19. Author Searching <ul><li>Question: Find an article by Dr Gawen RT Jenkin </li></ul><ul><li>Search on: </li></ul><ul><ul><li>Jenkin G* </li></ul></ul><ul><ul><ul><li>May or may not publish with middle initials </li></ul></ul></ul><ul><ul><ul><li>Journals may or may not other initials </li></ul></ul></ul>
    20. 20. Tools to Refine Results <ul><li>You can also use limits/filters to narrow your search </li></ul><ul><ul><li>E.g. by date or publication type </li></ul></ul><ul><li>Can include before or after a search </li></ul><ul><li>Helps avoid potentially overwhelming levels of results </li></ul><ul><ul><li>Easier to chose the pick of the crop </li></ul></ul>
    21. 21. Improve your Internet Searching <ul><li>Use more than one search engine as they use different searching algorithms </li></ul><ul><li>Use the advanced search features in Google & Yahoo </li></ul><ul><ul><li>Phrase searching </li></ul></ul><ul><ul><li>Search a specific field e.g. title or URL </li></ul></ul><ul><ul><li>Limit by language, file type, domain </li></ul></ul><ul><li>Use the options for specific media e.g. images, groups, news </li></ul>
    22. 22. Google Scholar <ul><li>“ Search specifically for scholarly literature ” </li></ul><ul><ul><li>No definition as to what Google classify as scholarly ! </li></ul></ul><ul><ul><li>Can be some odd gaps/omissions </li></ul></ul><ul><li> </li></ul><ul><li>Often links to full text but might not link to the version of the full text available to the University </li></ul><ul><ul><li>On-campus it will give you an e-link option to check whether you can access the full text for free </li></ul></ul><ul><li>Good first place to see what is available and what keywords to use </li></ul><ul><ul><li>But use bibliographic databases in your subject too! </li></ul></ul>
    23. 23. Open Access Research <ul><li>A move from academics annoyed over journal prices </li></ul><ul><ul><li>No passwords, subscriptions or access restrictions </li></ul></ul><ul><li>Researchers make articles available for free (outside of journals) </li></ul><ul><ul><li>Held in online repositories </li></ul></ul><ul><ul><li>Still include peer-review elements </li></ul></ul><ul><li>Can easily be searched using Open DOAR </li></ul><ul><ul><li>http:// </li></ul></ul>
