Lost Symbol information on Twitter: @lostsymbol
Just noticed that Dan Brown's website has had a *major* makeover. On the new site is a placeholder for an upcoming 'Symbol Quest' (probably, like the previous webquests, based on the codes on the cover of the book). Also on the new site is a PDF of the book cover for The Lost Symbol, which also shows the spine of the book - and more hidden codes. As such, I've updated my article on the codes hidden on The Lost Symbol book cover to include the latest discoveries.
One thing worth noting is that the very nicely-designed keyhole on the spine has an image of the Washington Monument embedded within it. More D.C. scene-setting, or an indication that the Washington Monument is going to be 'key' to the plot? The Solomon Key, as it were....?
