|Uniqueness relates to the amount of primary information
contained within the resource which is not obtainable from other sources.
On the Internet many resources contain little
primary or original information. Resources often contain only
secondary information - information about information - and simply link
to resources held externally on other servers. It is also common
for resources to repeat information that is available elsewhere.
A resource containing primary information that is unavailable from other
sources, and in particular other online sources is likely to be of greater
value than a resource containing secondary information, unless there has
been significant value added.
Imagine doing a search - getting thousands of hits
- only to find that they all contain very similar information, either with
text that has been lifted from other sources or with no primary information
at all - only links to other sites. You may end up going round in
circles by following the links and have to look at many pages before you
find any original information.
does the resource contain any original work?
is there some primary information on the site?
does the resource consist of more than a list of
links to external sites?
to look for:
if there are links to external sites, has some value
been added, such as annotations?
check the URLs of links to see if they take you to
information within the site or to external sites created by somebody else
the "About this site" links often lead to clues about
the uniqueness of the information
