If the links refer to some kind of "real" document (a journal article, a directive, etc.) rather than something like a blog or forum post, maybe it has an associated
DOI. If that's the case, you can simply use the DOI number (and even construct the target address as http://dx.doi.org/
DOI)
In other cases, maybe you can indicate the title or search term, if that makes it possible for the user to easily get there. For instance:
Code:
Wikipedia entry for "<a href="http://en.wikipedia.org/wiki/Digital_object_identifier>Digital object identifier</a>"
The user can click on the link or enter the article title in Wikipedia (which we'll assume the user knows how to get to), no need to write the full URL.
