Searching the Web | web directories

Directories are guides compiled by human indexers who assign subject headings to describe the contents of web sites. Searching a web directory is similar to browsing the table of contents of a book or the telephone yellow pages. One tries to decide how someone else might have classified information by browsing categories.

Yahoo.com , like CINAHL, organizes information in hierarchical categories. It is possible to locate Web sites in Yahoo by browsing (or "drilling down" ) through the hierarchies.

In the example shown above, Yahoo provides links to several sites devoted to Florence Nightingale, including one with the full text document, "Florence Nightingale: Rural Hygiene," an essay written by Nightingale on the subject of hygiene.
