imported from the web, are automatically stored in the
web-based citation management tools. If the searched
item does not have a permanent location on the web, it

and/or modified. Therefore, this kind of information
is important. These are designed to capture visual and
audiovisual information on the web. This function greatly
extends the ability to retrieve information, shared by a
group or collaborative work.
