It's an unfortunate fact that the internet has gained a bad reputation when it comes to provenance/attribution of 'old things' (probably all old things) - which isn't a situation that should exist, and is an irony in any case, in view of the mostly reliable available literature published in the last twenty five years.......... but that's to ignore human nature, again.
Outside of those (like us perhaps) who have a genuine interest in the history and aesthetics of our past, there are many on the internet who flout
any sense of accuracy to simply make a quick profit - so yes, I'd agree that electronic communication has severely dented the reliability of buying on line. Auction houses are little better .............. another source of history where the common denominator is profit and not accuracy.
Remember the incident earlier this year with a well know Midlands auction house who seem to have been ready to put their lives on the line over a certain 'T/Webb' attribution - and I never did hear back from them - which would appear to support the comment ... "with absolutely no primary reference to support those claims."
The internet seems to have been a heaven sent vehicle for those who have little or no interest in historic accuracy.
Is there a valid argument to say..... "this is my living and I can't afford the time to check details or acquire all the books necessary to find the correct attribution/provenance." - probably not, but the tide is too powerful now to stop, sadly.
Visit most 'antiques' fairs/markets these days and you can almost count the genuine antiques on the fingers of one hand - in fact I'm often the oldest thing there!
I understand that some original pressed glass moulds have been re-used (particularly on the other side of the pond??) - and are these modern pressings sold as being not antique?? - I suspect not.
quote .................... "or perhaps a failure to recognise constructive criticism?

" .......... I could be way off beam m, but if this comment was aimed at Manley's effort, then I don't think it's really appropriate in the context of all that we're saying now............ no doubt that in the late 1970s - and earlier - when he was compiling his book, there was little opportunity for external eyes to criticise his words, in the way this might happen now. It's probably only been in the last twenty years that the errors have come to light - the GMB wasn't around when Manley might have needed us

.
I wouldn't part with my copy - the pix are great, and it was his book that helped me with the history and attribution for the uranium Derbyshire goblet (item 354) - see page 37 - long before I was a habitual visitor to Kew ........... this piece is now I think with another Board member.
In his acknowledgments, Manley doesn't mention using what we now know as the National Archives at Kew (they were then the Public Record Office), and information was vastly more difficult to access............ and just think of the level of conversation his work has generated, so can't have been all bad.
