Most
information on the Web does not go through a review process.
Anyone can publish on the Web without passing the content through
an
editor. Pages might be written by an expert on the topic, a journalist,
a
disgruntled consumer or even a child.
Very few scholarly materials are free
on the Web.
Many
commercial websites, however, provide "free" information to promote
sales more than
to provide accurate
information, and they usually include
numerous advertisements.
All information
on the Web is not organized.
Some directory services, like Yahoo, provide links to sites in subject
lists.
But there are too many Web pages for any single directory
service to
organize and index.
Materials on the Web can disappear
suddenly.
Some well-maintained sites are updated with very current information,
but
other sites may become quickly dated or disappear altogether
without
much, if any, notice.
