I did a rough count yesterday, just of the books I own or have borrowed in physical book format, and could see from where I was sitting at the time or could remember off the top of my head, and did a conservative estimate in that I didn't count things I've read but am likely to reread, and didn't count the e-books I own, and I still concluded that I still have books for at least one year here, assuming it's on par with my most active reading years. And of course, the e-library is still open...
