The material on Web sites goes through no editorial process. Anyone can publish on the Web, and material does not have to be updated or maintained. In order to select high quality material,evaluate the Web site you plan to use in your research paper. Print the page(s) you cited, because Web material can change daily.
Not all published information is on the Web. The best information for your research paper may be available only in print format.
Since search tools are searched differently and return different results, use at least two different information formats in your research. (Example: Online database and print source)
Remember: no single search tool indexes all of the Web.
Meta search engines attempt to search several different Web search tools (both search engines and subject directories) with one search. The problem with these search tools is that they cannot take advantage of unique search features within any tool.
