I was directed to a great site the other day TheGM.org has a great utility called Perram's Spellbook, that allows you to print out spells on cards of varying sizes that are easy to take with you and eliminates the constant page flipping that all you wizards and clerics out there do.
You can print them out as 3"x5", 4"x6" or playing card sized that fit nicely into those Magic: The Gathering card sleeves. Granted, there are a few spells that have extra long descriptions that require multiple cards to get the whole thing, but its still a really inventive and handy utility.
Also, it has the option of inputting your own spells to create your own cards. It looks like it's catered directly for Pathfinder, but I don't see a problem inputting the few spells that may be different between Pathfinder and 3.5.
And don't even think of using Bigby's Inappropriate Hand, I already have the copyright.
