Geologyandsociety Presentation Transcript

  • 1. How to get Information forYour Geology Assignments Gareth Johnson gareth.johnson@le.ac.uk
  • 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.” - Westheimers 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. Author/Title – Use the ______________________ search• Books by Philip Kearey Author – Use the ______________________ search• Books on volcanoes Word or Phrase• - Use the ___________________ search
  • 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 Article Title Journal Title• An ____________ & a _____________ Volume Number Issue Number• A ______________ & an ___________
  • 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 Ore Ores Ore* Orebody•Saves typing!•Picks up multiple terms from foreshortenedword-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 OpenDOAR – 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?
