Karen, * - Identities in WorldCat are based on literary warrant, i.e., names for people who authored/edited something or were subject in someone else's literary work. Personal names in WikiPedia are not entered according to literary warrant. Nor is their form vetted according to NAF. - Ludvig van Beethoven doesn't need much disambiguation. Nor does Mark Twain. - So yes, Karen/Ralph/Tom -- how exactly is Wikipedia used for disambiguation? are you certain it's used for THAT purpose? if yes, can you send us a proper example? Morris, William seems a good example. Ya'aqov * * * * * *On Thu, May 19, 2011 at 3:48 PM, Graham Seaman <[log in to unmask]>wrote: * > > *Hi Karen > > Thanks for the code.
