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