How do you guys keep your songbooks?

I like having my songs printed out and nicely laid out so that I don't have to flip pages while playing and I've just updated my songbook with some new songs today and there is literally no more space in my binder, I have over 250 songs rn and I'd like to keep them all together, because I feel the need to have all the options available, but that is less and less of an option with every song I add. I think having a tablet would fix this, with also the benefit of seeing the songs in the dark around a campfire, but I just like the paper more, albeit that's just a little irrational preference of mine.

So my question is, if you have a physical songbook, how do you organize your songs and how many songs do you usually carry around?
