    Making the Most of Google for Healthcare - Presentation Transcript

    1. Making the Most of Google Jason Curtis Electronic Resources Librarian Shrewsbury and Telford Health Libraries
    2. Learning Outcomes
      • By the end of this presentation you should:
      • Know about some of the services Google offers
      • Know about some of the advanced search tools
      • Know about some of the limitations of Google
    3. What is Google?
      • One of a number of search engines that aim to index the whole internet
      • It has indexed over 25 billion web pages, including file types such as Word and PDF documents and Excel spreadsheets
      • Google attempts to rank results based on presence of keywords searched for and links to page from other sites (PageRank)
    4. Google’s Limitations
      • It is not able to index much information contained within databases, catalogues etc. The so-called ‘deep web’
      • It’s results only as good as the information available – the quality of information found needs to be appraised
    5. What does it offer?
      • Some of the most useful services for health are:
      • Google Search (the first page you normally see)
      • Google Images
      • Google Scholar
      • Google Co-op (includes health pages)
    6. Google Advanced Search
      • Google Advanced Search allows you to:
      • Limit to English language only
      • Limit by type of file (such as Word or PDF)
      • Search for phrases (such as “allergic reaction”)
      • Exclude word (ulcers not diabetic)
      • Search by domain or site (such as nhs.uk)
      • www.google.co.uk/advanced_search
    7. Other Google search tips
      • Google search also offers:
      • Synonym searching (~angina)
      • Definitions (define:rosacea)
      • Limit to UK pages only using the checkbox on the main page
      • www.google.co.uk
    8. Google Images
      • Searches over 1 million images of variable quality and size
      • See www.library.nhs.uk/images for more resources for healthcare
      • www.google.co.uk/images
    9. Google Scholar
      • Aims to index material from academic journals, theses, books and other scholarly material covering all disciplines
      • Has some very limited options for field searching, date limits and publication searching
      • www.google.co.uk/scholar
    10. Limitation of Google Scholar
      • Not all academic journals indexed
      • Frequency of updates is unknown
      • No links to NHS e-journals
      • No information about locally held print journals
      • Lacks features such as combining searches, limiting to age group or publication type, saving searches or creating alerts
    11. Advantages of Google Scholar
      • Extremely quick and easy to use
      • Can sometimes throw up articles not retrieved in a database search (e.g. Medline, CINAHL)
      • You can see who has cited a paper
      • Useful for searches outside the field of healthcare, where the NHS has no access to appropriate databases
    12. Alternatives to Google Scholar
      • The National Library for Health provides access to databases including Medline, EMBASE, CINAHL, AMED, PsycINFO, HMIC, British Nursing Index and Health Business Elite
      • These offer advanced search features and provide links to NHS e-journals
      • www.library.nhs.uk/booksandjournals
    13. Google Co-op (including Health)
      • Pages can be tagged by bodies working in the field (such as the US National Library for Health)
      • A search for a basic medical condition will bring up a list of categories to choose from
      • Works well, but not perfect as not all useful pages tagged
    14. Google Co-op
      • Google Co-op also allows the creation of personalised search engines, for example:
      • UK Patient Information
      • http://tinyurl.com/25kcw6
      • Medical and Surgical Wikis
      • http://tinyurl.com/5g26w5
    15. Other Features
      • Currency conversions (such as ‘12$ in £’ or ‘£5 in €’)
      • Converting units of measurement (such as ‘12oz in grams’ or ‘150ml in cups’)
      • Calculations (such as ‘15% of 240’ or ’34.5/4’)
      • Translation tools that allow you to convert passages of text or web pages in selected languages
      • www.google.co.uk/language_tools
    16. Other features cont.
      • Personalised iGoogle home page that can contain search boxes, RSS feeds, news, maps and more
      • www.google.co.uk/ig
    17. Finally…
      • Google is not a replacement for resources such as healthcare databases, library catalogues or systematic reviews of evidence
      • Can be useful for ‘quick and dirty’ searches but should not be relied upon
      • Consider it one of a range of tools, and come along for training on the others available
