OpenBib does some neat things with wikipedia content http://kug.ub.uni-koeln.de/portal/connector/permalink/inst503/20791/1/kug/index.html There is no reason we can't do this too
A quick way is to put <a href="http://en.wikipedia.org/wiki/Special:BookSources/{ISBN}">Wikipedia ISBN Search</a> in OPACSearchForTitleIn
I think the correct link would be https://www.openbib.org/, but I didn't find anything on a Wikipedia integration. This bug is 12 years old, I suspect things have moved on.
