J-50 Lab 1

• Our agenda
• The Online Library Catalog
• Electronic Indexes and Databases
• Web Searching
• How Search Engines Work

2
After This, You Should be Comfortable

• Using online catalogs, indexes and databases.
• Using search engines and keywords to find
  information on the Web.

3
Online Catalogs

• The UNC-CH libraries have a fantastic collection
  of print and non-print resources that can help
  you research any topic.
• The online catalogs provide a way to search for
  the physical books, videos and other materials
  that the library owns or can find for you. See
  http//www.lib.unc.edu/index.html

E-indexes and Databases

• In addition to their collections physically
  housed at the library, the libraries also have
  extensive online versions of journal articles and
  other materials.
• The e-journal finder is a way to find electronic
  versions of articles from newspapers, magazines,
  journals and other publications when you know the
  publication youre seeking. (http//eresources.lib
  .unc.edu/ejournal/)
• The article databases allow you to search large
  databases by either choosing a database to search
  or finding appropriate databases by subject.

Keywords and Boolean Search

• Directed searching requires you to determine what
  part of a material you will search (e.g., author,
  title) and how keywords will be used to include
  and eliminate various materials to produce
  results most relevant to your aims.
• Boolean logic, which uses terms such as and,
  or, and not in conjunction with keywords to
  describe the relationships between how they
  should appear in the documents you seek, is a
  primary way to guarantee efficient and complete
  results. Without this type of guidance, your
  results may be incomplete and/or irrelevant.

Types of Search Engines

• There are many types of search engines, but they
  can be broken down into four primary categories
• Search Engines
• Meta-search engines
• Subject Directories
• Specialized Search Engines
• The chart at http//www.lib.berkeley.edu/TeachingL
  ib/Guides/Internet/ThingsToKnow.htmlTypesOfTools
  describes these types in detail and provides
  examples of each.
