I did a quick search and the library service in England costs 840 million per year for an entire country.

Or roughly $12/resident/year. Admittedly, England has also been cutting deeply into their social services budgets, with library spending falling by over a quarter over the last decade. The UK has lost over a fifth of its public libraries during this time and continues to cut deeper and deeper into these budgets. So its per-capita cheap, but also a popular target for enormous budget cuts.

Compare that to the city's police budgets and you'll find a yawning gap that's only growing larger with time.
