Well, English Heritage have just re-jigged their Silbury Updates page - that's probably cost a couple of hundred at least, so be grateful ;-) There's no new information from EH on that page of course but I'd sort of given up hoping that there ever would be. Never mind, when the archeos and those with secret and mysterious knowledge of what they think they recently saw in Silbury have recovered from their seasonal excesses I'm sure there'll be a plethora of 'scholarly' papers and wacky books to peruse. I can hear the tills ringing already :-)
