One thing I have used to great effect with two different groups is the use of a "spellbook". This is not some "Dark Lord of Denny's" or "Mazes and Monsters" affair with a real life version of the Necronomicon and two missing drifters.
This is a simple affair, a dollar store mini notebook. In the notebook between games I will jot down any spells the player learns (all the details). This means when casting a spell a player no longer needs to sort through a big book but can look through a simple journal.
I highly recommend it.
