In NGR it is incredibly important that wizard's try and keep their spells to themselves. Obviously over time sharing, stealing, apprenticeships and librarians ensure that some spells, or rather collections of spells, are more common than others. While I do also keep a different type of chart for random spells (unique or rare one-offs) this is a table for the more common grimoires in a table. The Cultes De Goules and the Necronomicons of a region.
For each rare book a collector or wizard MIGHT have roll a d20. For each more common tome roll 3d6. The mathematical reasons for this should be obvious.
