  1. Internet Searching: Tips and Techniques Vicki F. Croft, Head Health Sciences Library

  2. Objectives • To help you search the Internet more efficiently and effectively • To share selected free animal health-related web sites and information resources and other useful health and international web resources • To provide suggestions on ways to evaluate Internet sites and resources

  3. Outline • PowerPoint Presentation • Hands-on Searching • Discussion and Questions

  4. Definitions • Internet: a global network of interconnected computers. Includes email, the www, etc. • WWW (World Wide Web): a service that includes a collection of documents stored on computers connected to the Internet. The contents are written in markup languages, such as html, and often contain hypertext links for moving from document to document.

  5. World Wide Web (WWW) • Visible web: that part of the web that is searchable by search engines • Invisible or deep web: the non-searchable part of the web. It may be 2-500X as large as the visible web! • Proprietary information • Archival documents; older materials (pre-1980’s) • Library catalogs • Information/citations/articles from databases, etc. that cost money to access, e.g. Web of Science • Sites technically not accessible

  6. Ways to Find Information from the WWW: • Search engines, e.g. Google • Directories, e.g. Yahoo • Subject gateways, favorite sites/lists, such as Vet Gate • Specialized databases, such as PubMed, Agricola

  7. Search Engines • Search engines are powerful Web search tools that enable you to trawl vast quantities of Web resources by keyword searching. Results are ranked based upon computer completed indexes of words from web pages. • Examples: Google, DogPile

  8. Directories • Large, multi-subject search tools aimed at a general audience and built by human editors. • Quality of resources is variable • Usually use very broad subject hierarchies that take a lot of browsing, with no controlled indexing. • Examples: Yahoo, NetVet/Electronic Zoo, DMoz

  9. Subject Gateways • Designed to help users locate high quality Web resources in a particular subject area. Provide access to hand selected, evaluated Web resources, chosen by subject specialists and information professionals. • Organized by subjects for easy browsing. • Examples: VetGate, Free Animal Health Resources (Cornell)

  10. Search Engines vs. Directories, Favorite Sites, Gateways • Use search engines for finding more specific information (visible web) • Use directories and subject gateways for more general information and starting points • Use known web sites or specialized databases when the information is likely to be found at that web site, e.g. Pub Med Remember: No single search engine can capture all the information. More information is not always better.

  11. Hands on Practice • http://wsulibs.wsu.edu/hsl/icahis5/handson.htm

  12. Search Engine Strategies (Syntaxes) (http://google.com) • For exact phrase, use quotes “west nile virus” • By title In title: rabies bats • By URL url:www.aaep.org • By date bubonic seattle 1907..1908 • Exclude a word python –Monty • By language – use Preferences and select language(s), e.g. ZorroEnglish • Combining syntaxes, e.g. in url: www.aaep.org navicular

  13. Veterinary Web Site Gateways • Free Animal Health Resources (Cornell) http://www.vet.cornell.edu/library/FreeResources.htm An excellent, annotated, up-to-date web site of free internet resources, arranged by category. Includes hints on searching, and evaluation of web sites. • VetGate: Internet Resources for Animal Health http://vetgate.ac.uk UK-based, from BIOME, a free internet service that provides access to Internet resources in health and life sciences. Linked sites have been selected and evaluated by experts. Includes a nice tutorial.

  14. Quick Answer Reference Sites • Internet Public Library http://www.ipl.org Provides links to general reference, quick answers. Ready Reference section has good links to almanacs, dictionaries, encyclopedias, acronyms, etc. Useful if you don’t know the URL. • Yahoo! Reference Collection http://www.yahoo.com/reference • Google Images http://images.google.com Includes over 800 million images. Can limit by size, format, color, domain • All the Web http://www.alltheweb.com Images, video, and audio searching

  15. Free Searchable Databases PubMed http://pubmed.gov Contains references with abstracts to articles in over 4,300 biomedical journals published internationally and covering all aspects of medicine. Includes indexing to more than 80 veterinary journals. Updated daily. Contains links to some free online journals. Some references go back to the 1950’s. For a list of veterinary journals indexed in PubMed, go to: http://www.systems.wsu.edu/bin/libdocs/periodicals/VetJournalsPubMed.pdf

  16. Help Guides to Searching PubMed • PubMed Tutorial http://www.nlm.nih.gov/bsd/pubmed_tutorial/m1001.html A Web-based learning program that shows how to search PubMed • PubMed Searching: Veterinary Medicine http://www.lib.vt.edu/services/branches/vetmed/VMLS/VMLS%20PubMed%20brochure.pdf Helpful hints for searching for veterinary topics in PubMed • PubMed Search Tags and Field Qualifiers http://nnlm.gov/ner/PubMedFieldTags.doc A handy chart of tags and field qualifiers.

  17. Free Searchable Databases Continued AGRICOLA http://www.agricola.nal.usda.gov Contains approximately 3 million citations in agriculture and related topics from 1970 to present.  It is maintained by the U.S. National Agricultural Library in Beltsville, Maryland. Best for food production animals, animal husbandry and feeding, as well as other aspects of agriculture.

  18. Evaluating web sites: • Where? • Why? • Who? • Current? • Author’s credentials? • Reliability? Accurate? • http://snopes.com • Organized? Easy to navigate? Clear?

  19. When you are looking for something and can’t find what you need… • Is online the best place to look? • Should I try a directory or search engine? Which one(s)? • Who is most likely to have the answer? • Have I looked the right places with the right tools? • Have I overlooked some important resources? • Is my search too narrow? Is my search too broad? • Any misspellings? Have I used correct syntaxes?

  20. Creating and Maintaining Your Own Favorites • Bookmark favorite sites in your browser, e.g. Internet Explorer • Create a list in Word with hotlinks • Include your websites on your libraries web page • Suggestion: Check links, look for new sites and links every 6 months Free automated link Software: www.linklint.org • Open Source Perl Program • Includes Documentation
