I find exactly one attestation in print, none in Google Groups. —Michael Z. 2009-07-28 02:58 z 

Is a photo of a conference poster a valid attestation? It appears to be a print publication on durable media—the photo is proof of its existence, but I don't know if a single copy has been archived anywhere—it's not likely to be found in a library. —Michael Z. 2009-07-28 05:32 z 


 * I think a poster can be considered as durably archived as a book is. However this one mentions the term, doesn't help to understand it's definition, and even then, it would only be one cite. Entry fails. Mglovesfun (talk) 21:48, 6 January 2010 (UTC)
