Doh! I see them now
I think that a lot of the spells in Dreams of the Red Wizards reappeared in Pages From the Mages; but there is a lot of reprinting here and there. A few spells even had their names changed... And some spells either entered generic AD&D from the FR or vice versa... (i.e. Strength of Stone, a 1st level priest spell, in FR is restricted to certain priesthoods only)
Nice long list so far
One thing about the Realms, is that there are LOTS of extra spells and such - a lot of them somewhat unbalancing (in terms of game balance), but...
