If it were me, I would probably set the days on the calendar that we go to the library (2-3 times per week). I would set a timer and let him spend X number of hours at the library, and he could check out X number of books. I would probably also introduce some sports/crafts/outdoor hobbies (or whatever floats his boat) just for diversity to make him as well rounded as possible. Is he going to school or are you homeschooling him? You may also want to check out some gifted programs locally and some gifted forums online (most of the parents on his forum have not yet reached this point so our input may not be as helpful). This might be a good place to start

Great job to the both of you! What words of advice do you have to parents who are currently on this journey of helping their kids read early and creating a lifetime love of books?
I just reread this and it may come across that this approach would stifle the child's growth. Reading is WONDERFUL, the cap would only be for *my sanity* so take my advice with a grain of salt. haha Hmmm...what if you allowed him to get into reading more technical books and starting to apply those concepts to build things?? Simple machines, radios, etc.
