From Surfing to Searching: a planned approach by Mrs. Sh@n@h@n
There’s a Chinese Proverb that says… • You can give a man a fish • or you can teach him how to fish.
Today we find out where to find the best catch!
Are you ready? !?
Let’s Go !!!
Spring into Inquiry – Boing! You Are Here Stripling, Barbara K. 2003. “Inquiry-Based Learning. ” In Curriculum Connections through the Library, ed. Barbara K. Stripling and Sandra Hughes-Hassell, 3 -39. Westport, Conn: Libraries Unlimited. Accessed on http: //www. flickr. com/photos/23346165@N 03/2304444220/ on 11/19/09.
On your mark, get set, GO!
Where to Start? • Consider your topic. What is the issue? How large is the scope? (e. g. town, county, state, national, international) Are there comparable instances? – All of this is relevant to your search • What are the keywords? – Think in Boolean terms and kick out the “noise” (e. g. “farmers + america” versus “farmers in america”)
Free Web Search Engines and Strategies • Sure – Here are the regulars! – Google – Bing – Yahoo! • Strategies – Use Advanced search option – Operators – Modify keywords based on results – “Put phrases in quotations” – Select “Similar” to pearl grow
For example
We know that Mrs. Sh@n@h@n! We search all the time.
Yes - but there’s more… There also hybrids, aggregators and hidden databases known as the “Invisible Web” or “Deep Web” which is not indexed by standard search engines
OED • Deep Web Search Engines • To get started, try using a search engine that specializes in scouring the invisible web for results. None of these can search the entire invisible web, but they make some inroads that Google has not as of yet. • Clusty — A metasearch engine that combines the results of several top search engines. • Intute — A searchable database of trusted sites, reviewed and monitored by subject specialists. • INFOMINE — A virtual library of Internet resources relevant to university studentsand faculty. Built by librarians from the University of California, California State University, the University of Detroit-Mercy, and Wake Forest University. • Librarians' Internet Index — A search engine listing sites deemed trustworthy by actual human librarians, not just a Googlebot. • Internet Archive — A database of tens of thousands of movies, live music, audio, texts, and home of the Wayback Machine that allows you to find old versions of web pages, over 55 billion. • direct search — A list of hundreds of specialty databases and search engines. No longer maintained, but still perhaps the most complete list of the deep web. http: //oedb. org/library/college-basics/research-beyond-google, last accessed 11/19/09.
Oh, I see. We just missed some of the information on the internet. Now we’ll have everything we need!
Not so fast. Did I mention subscription databases? • Subscription databases house a collection of publications. The database aggregates the publications and provides one interface through which we access the information. • Typically, databases are information stores of quality, scholarly journals (peer-reviewed and non-peer-reviewed), reference sources where information has been collected, reviewed and edited by professionals for accuracy. • Fee based – INFORMATION IS VALUABLE!
Why Use Databases? Minimizes Bias • The free/open web has informally published work that may contain distinct points of view or bias. While a site might help you better understand stakeholder concerns, it may only present one position. Furthermore, it doesn’t necessarily equate to a position based on valid facts. Improves Efficiency • Time is of the essence! - A Google search may give you websites that are from a number of years ago or that haven't been updated in a long time. Databases are updated frequently – that’s why we pay a fee. • A note about blogs – while useful at times, blogs appear regularly in Google searches. Some may prove to be useful – however, they also require a lot of time to read! Heightens Accuracy & Readability • Proofread, professionally published documents.
Here’s a few of our subscription databases Literature Biography History Science
Database Search Strategies • Subject Thesaurus • Operators • Truncation Symbols • Broaden or narrow search (e. g. “gay marriage” vs. “gay marriage” and “new york” or “economic impact” • Pearl grow • Spelling Counts! – Not all search engines and databases will offer spelling alternatives. If in doubt – look it up.
Image Search • Select portals and images labeled for specific types of reuse (copyrightfriendly. wikispaces. com/) • Use verbs and descriptive language to evoke rich results • Consider the audience and represent various viewpoints • Select images of appropriate size (pixilated images look sloppy!) • Query specific format JPG, GIF, or PNG
So, class, did you learn anything? !?
We learned _____! And…
