Naperville Public Library Hours for All Three Branches

The Naperville Public Library runs three full-service buildings: Nichols Library downtown, Naper Blvd. Library on the city's southeast side and 95th Street Library in south Naperville. They share one schedule Monday through Saturday, which makes the library easy to plan around on most days. Each table below shows the regular weekly hours for one location as published by the library for 2026.

Regular hours apply unless the library lists a closing or an early closing for that date. Those are covered in the holiday section below and, in more detail, in our Naperville library holiday closures guide. For what each building offers beyond the hours, see the branch-by-branch guide.

Sunday is the only day of the week when the three Naperville libraries keep different hours. Every location opens at 1 p.m. What changes is the closing time:

Right now (November 2026) the school-year schedule is in effect, so Nichols and 95th Street are open until 9 p.m. on Sundays and Naper Blvd. closes at 5 p.m. The shorter summer Sundays begin in June. If you are planning a Sunday-evening study session, a downtown or south-side branch is the one to choose.

Adding it up, Nichols and 95th Street are each open 76 hours a week from September through May (60 weekday hours, 8 on Saturday and 8 on Sunday) and 72 hours a week in summer. Naper Blvd. is open 72 hours a week all year, because its Sunday is always four hours long.

If you only need to collect items on hold, curbside pickup lets you stay in your car. It is offered at all three locations and ends 30 minutes before each building closes:

The library publishes a full-year list of closings. These are the changes still ahead in 2026, as listed on November 3, 2026:

Earlier in 2026, all locations closed on New Year's Day, Easter Sunday, the Sunday and Monday of Memorial Day weekend, Independence Day, a staff training day on August 28 and the Sunday and Monday of Labor Day weekend. Nichols Library alone closed on September 4 and 5 for the downtown Last Fling festival and opened at 1 p.m. on March 14 for the St. Patrick's Day parade and race.

The 2027 closings had not been posted when we checked. Our holiday closures and special hours guide keeps the full 2026 calendar and explains what to expect while the 2027 dates are pending.

The details below are the Naperville Public Library's official public contact information, taken from each location's page on naperville-lib.org. The main library number, 630-961-4100, reaches the library during regular hours; the Customer Services line goes straight to a specific building.

Knowing the open hours is the first step. A few library rules affect how much you can get done in the time you have:

• Study rooms are free and first come, first served at all three locations. You sign in, and the time limit is an hour and a half per use, which staff may extend if nobody is waiting. They cannot be booked ahead.
• Conference rooms can be reserved by any Naperville Public Library cardholder for $10 an hour, up to four hours a day. Meeting rooms require an adult cardholder and a reservation made more than 10 days ahead. Details are in our library services guide.
• Public computers are open to all customers whether or not they hold a card, and Wi-Fi is provided for your own devices. Black-and-white printing costs $0.10 per side.
• 3D printing takes up to 7 to 10 days and is picked up at 95th Street Library, so allow time before a deadline.
• Parking at Nichols can be tight. A July 2026 NCTV17 report put the library lot at 130 spaces, and a parking deck is still only a proposal. Curbside pickup or one of the other branches can be easier at busy times.
• No card yet? Incorporated Naperville residents 18 and older can register online. Our Naperville library card guide covers residents, unincorporated households and reciprocal borrowers.

Unplanned closings can also happen. The library posts schedule changes on its Hours, Holidays, and Closings page, so it's worth a quick look before a long drive, especially around holidays and big downtown events.
