Cincinnati and Hamilton County's public libraries add Wi-Fi: There's service at the downtown branch and 41 county branches. Service is charged at $4.95 per hour or $9.95 for 24 hours, and it's run by Cincinnati Bell. Can I note how rare this is? Very. Most libraries absorb the cost of Wi-Fi as part of bringing in more users who in turn are more likely to donate to the system, vote for bonds, or otherwise support the library as a critical resource that needs funding.
