  2. Expert Online Searching Techniques Work in Library Databases or on the Web

  3. What Is a Database? da·ta·base noun \ˈdā-tə-ˌbās, ˈda- also ˈdä-\ :  a usually large collection of data organized especially for rapid search and retrieval (as by a computer) "Database." Merriam-Webster.com. Merriam-Webster, 2014. Web. 11 July 2014. <http://www.merriam-webster.com/dictionary/database>.

  6. About Records • Records represent real items. • Records are not the real item itself (in most cases). • Records are formatted. • Records are made up of pieces called fields. • Records are more easily searchable than the real item.

  14. Characteristics of Useful Keywords • The rarest words • The most specific words • As many forms of the words as you know

  15. You Put In a Keyword or Search Term;The Computer Matches It Exactly in the Records Keyword Records

  16. “Little Words”, Called “StopWords”, Are Often Not Searched A, an, of, the, from... In, on… …and so forth

  17. Why Not Use Stop Words? Stop words are so common in human language that they do not add any meaning to an online search. Google parses full sentences and filters out stop words, but other search software requires you to do the filtering.

  18. Keywords Can Be Combined OR AND

  19. “And” Makes Searches Smaller Learning AND Organization

  20. Exact Quotes Imply “And” Plus Word Order Public and Administration “Public Administration”

  21. “Or” Makes Searches Bigger jobs OR employment

  22. Truncation Marks Imply “Or” architect*(?, #, $) yields architect architects architecture architectural

  23. Subject Headings

  24. Library Databases Often Include Descriptors or Subject Headings as Well as Simple Keywords

  25. About Subject Headings Subject headings are often assigned by human beings. The words in a subject heading might not appear in the item itself. Items on a similar subject are retrieved together by their subject headings.
