  1. Search Techniques L. B. Chouhan

  2. What is E-Library? • E-Library refers to all the library resources that are available online through computers and databases. These are different than the open internet, as they have restricted access. Students and faculty can access the articles, databases, books, services, and resources through E-Library. • You will need your ID and password to access many of the online library resources.

  3. Search Techniques Several techniques for database, catalog and Internet searches include: • Boolean techniques • Truncation • Phrase Searching

  4. A B Boolean Search Boolean search techniques work in databases and on the Internet. Use keywords in a variety of ways to refine your search. A and B stand for key words or phrases. The words “AND,” “OR” and “NOT” are called logical operators.

  5. B A A B B Boolean Search AND: When you use “AND” between two terms, your results will include sources that show the two terms together in a source. A OR: Use “OR” to broaden your search by looking for several terms in a source whether they appear together or not. NOT: Allows you to reduce the number of results you get from a search. This can be helpful if you want to exclude results related to your topic but not relevant to your thesis.

  6. Truncation • Use the root of a word to broaden your search responses. • Using the root Psych* will result in the following: • Psychology • Psychological • Psychologist • Psychiatry • Psychiatrist

  7. Phrase Searching • Using quotation marks (“”) makes it possible to search for important phrases instead of individual keywords • Phrase: “San Francisco Earthquake” • As Keywords: San Francisco and Earthquake • Phrase: “Welfare Reform” • As Keywords: Welfare and Reform • Phrase: “Community College” • As Keywords: Community and College

  8. Examples • Using AND, OR, NOT, with * and “” • “Coll*” AND “Welfare Reform” OR poverty NOT welfare • Some databases or search engines may use symbols in place of the Boolean terms: • “Distance learning” + (and) technology - (not) computers

  9. Internet • The Internet can be useful as a research tool • The large majority of Internet sites are for commercial purposes and frequently are less valuable as a source of information • Unlike databases, no authoritative entity reviews and evaluates material on the Internet • The researcher must carefully evaluate information retrieved from the Web

  10. Internet Search Suggestions: • Try different search engines • Use a variety of keywords • Use Boolean techniques, truncation and phrase searching • Carefully evaluate web sites • For more on evaluating web sites, visit the CCC Library “Handouts & Workshops” page and review “Critical Thinking and Evaluating Web Sites” handout • Use the search engine “Help” menu to save time

  11. Library Catalog • Library catalogs allow a student to search for all types of materials • Available resources include books, periodicals, audio/video resources, databases, web sites and other electronic resources • Electronic catalog searches help with time management
