The only way you can have too many RPG books is if you're physically unable to store them in your home or apartment.
I get where you're coming from but I refuse to part with the books I've collected over the years, even the ones I don't use often or never made it to the table. The only games I've parted ways with were either games that were stolen from me or physically disintegrated due to heavy use + poor construction, and in almost every case I regret not replacing them immediately. Some of them are long out of print and can't be easily acquired anymore, which is going to be even more common in the future with so many games being published only via Kickstarter fulfillment or as a PDF.
