The Book of the Tomb, an AO document comprising a series of instructions (including a Flying Roll) on the construction of the Vault of the Adepti, has been published online by Nick Farrell on his website and can be found here. Some of it has already been in print, including in Regardie's black brick, but this copy is much more complete, with a number of illustrations to boot. This is a very important document for all Golden Dawn orders, especially those currently attempting to construct a Vault.
