The true value in the DISPLAY_856 wwwoption controls whether or not 
the link opens in a new window.  The links themselves display 
automagically -- no wwwoption is needed to make them display.  (If 
using bib_display.html, you need to use the "URLS" token in order for 
the links to display.)

If the question is how to make the URL itself display as the link 
text, you can alter the first parameter of the display_856 wwwoption 
to use the subfield where the URL is located as the link text (presumably $u).

If the question is how one can make the content of an 856 field 
display in the same way that content from other MARC fields display, 
AFAIK, the answer is that as long as the fields are y-tagged, you 
can't.  Most y-tagged fields can be made to display by accounting for 
them in webpub.def and bib_display.html (assuming you're using one or 
both), but the 856 field appears to have a mind of its own in this 
regard -- I have not been able to get a y-tagged 856 to display this 
way.  If you change an 856 field's field group tag in the MARC record 
to something other than y, you can get its content to display, but 
then you lose the link table.

You could always duplicate the 856$u in a notes field, or use 
Javascript to grab the URL from the source and write it somewhere 
else in the record.
