Using Search Engines and Subject Indexes to Locate Federal Information |
With the amount of government information appearing on the WWW growing at a phenomenal rate it can be very difficult to find what you are looking for -- even if you know which agency produces the information. Fortunately, there are many powerful search engines, subject indexes, and WWW pages designed to assist you in finding a particular government information resource. These resources vary significantly in their coverage. The following tutorial is designed to assist you in effectively using these resources to find what you are looking for and will help you answer the questions below.
Search Engines:
Search engines allow the user to enter keywords or phrases that are run against a database created automatically by spiders and robots. The search engine retrieves information based on two things: your query and how the search engine gathers the information. Since all the top Internet search services operate differently you must use several search engines to do a comprehensive search.
Subject Indexes:
Subject indexes are hierarchically organized indexes that allow you to browse through lists of WWW sites by topic. They are selective lists of WWW sites that require some degree of human oversight whereas search engines automatically gather information. Generally, subject indexes are smaller than search engines. Because there is human oversight subject guides can save the user time by reducing the amount of irrelevant information.
