Can you place GNU permission for copying your Pokorny Lexicon... at the same place... to enable copying and redistributing it under GNU GPL...?
I am sorry, but there are two problems that prevent me from giving you permission to republish our Pokorny web page:
Therefore my answer must, for the time being, be "No, you may NOT copy or republish our content under the GNU GPL."
Since the page/content you refer to will remain online, for many years into the future, there is no reason why you or anyone should reproduce it. University of Texas web servers are highly reliable and always available -- probably more so than your own website! All you need to do, to make this content available to your website visitors, is put a link to my page from your own page. That is the beauty of the World Wide Web.
If the University of Texas web servers were often down, I might be more sympathetic (although reasons #1 and #2 above would still apply). But there is no reason to copy content from a site with essentially 100% availability and very strong backup procedures.
