Details of more than 40 spellbooks - appearance, history, the magic they contain, and what is known of the fates of their makers.
And just for fun - Elminster's very own travelling spellbook.
"All this could have been avoided, of course... If the handful of heedful folk in the worlds'd listen to me but a few moments more, much trouble could be averted - and, I suppose, much high adventure. Hmmm... perhaps 'tis the doom of humans to always rush in heedless of the costs - and to open and read every old, crumbling book they find." - Elminster
