Libraries have long offered free internet access and public computers, and many now go further. Some lend portable Wi-Fi hotspots you can take home, along with laptops or tablets for short-term use. This can help if your home connection is slow, unreliable or too expensive to keep.

Meeting rooms and study rooms are another overlooked perk. Many branches let community members reserve a room for tutoring sessions, club meetings, remote job interviews or simply a few hours of focused work. For people who work from home, it can be a free alternative to a coworking space or a daily coffee shop habit.

Check your library's policies on reserving rooms and borrowing devices, since they vary. When using public computers or Wi-Fi, avoid logging into sensitive accounts if you can, and always sign out when you're done. With a little planning, the library can become a reliable second office that costs you nothing but the trip.
