Web Concerns: No Subject Headings
Encountering useless web pages are only one problem in using the Internet for research. There are many other major issues.
One problem is that nearly all search engines lack the sophisticated search capabilities that both library catalogue and databases provide. You can't do a search on a subject heading in Google because it doesn't include subject headings. It just searches the full-text of web pages. Because of this, searches will often return results of thousands and thousands of web pages.
You will get better search results
using subscription databases and library catalogue rather than
Internet search engines such as Google or Yahoo!.
