I found out that the following search string works with AltaVista,
AlltheWeb, Yahoo Search and Lycos (Inktomi) in addition to HotBot (Inktomi):
'linkdomain:wu-wien.ac.at NOT domain:wu-wien.ac.at'

Here is his very valuable information...
Looks like HotBot (http://www.hotbot.com) gives inlink counts for whole
sites for search strings like:
linkdomain:www.db.dk and domain:uk
(with your home page as no 4 on the result list :-)

Link counting in AltaVista and AllTheWeb no longer work, since the buyout of both by Yahoo!.
Links between web sites can be counted in google, e.g.
+"www.goldsmiths.ac.uk/departments/computing/" -site:goldsmiths.ac.uk
But this only works for URLs that appear in the *text* of the page.
Does anyone have any better ideas for link counting to whole Mike Thelwallhttp://www.blogger.com/profile/11997243815649603823noreply@blogger.comtag:blogger.com,1999:blog-5762907.post-1066221763670625932003-10-15T13:42:00.000+01:002003-10-15T13:42:43.420+01:00Most cited LIS authors 2002-2002 See the "www-metricians" in Olle Persson's map.Mike Thelwallhttp://www.blogger.com/profile/11997243815649603823noreply@blogger.comtag:blogger.com,1999:blog-5762907.post-1065004814285728542003-10-01T11:40:00.000+01:002003-10-01T11:40:13.840+01:00JCMC Vol 8 Issue 4: Internet Networks: The Form and the Feel: "Internet Networks: The Form and the Feel" Journal of Computer Mediated Communication special issue.Mike Thelwallhttp://www.blogger.com/profile/11997243815649603823noreply@blogger.comtag:blogger.com,1999:blog-5762907.post-1062598946280454592003-09-03T15:22:00.000+01:002003-09-03T15:22:26.310+01:00WISER - Web Indicators for Science, Technology & Innovation ResearchMike Thelwallhttp://www.blogger.com/profile/11997243815649603823noreply@blogger.comtag:blogger.com,1999:blog-5762907.post-1062594755214933052003-09-03T14:12:00.000+01:002003-09-03T14:12:35.276+01:00Web impact factors for libraries in a Brazillian stateMike Thelwallhttp://www.blogger.com/profile/11997243815649603823noreply@blogger.comtag:blogger.com,1999:blog-5762907.post-1062594452784014482003-09-03T14:07:00.000+01:002003-09-03T14:07:32.856+01:00Cybermetrics.
