A library in Delaware built a sensory room with Autism Delaware, and it was noted as the first of its kind in a U.S. public library. Visitors can adjust the stimulation level to fit how they feel.
I love that idea so much.
Another library in the state sits under a rooftop solar array designed to cover its entire electric use. A third can accept your passport application.
Yes, at the library.
None of these places charge admission. Your library card does the heavy lifting, and some perks don’t even need a card.
So I started digging for the spots that stretch the idea of a library the furthest. Some sit near the beach, and others anchor busy downtowns.
Let us know which one you visit first.
1. Lewes Public Library

Few libraries can say the sun handles their electric bill, but this one comes close. A roof-mounted solar array was designed to offset 100% of the building’s electricity use.
That fits a place billed as the busiest library in Sussex County. The 28,500-square-foot building opened in June 2016, and it holds more than 50,000 items.
Teens get the best toys here, honestly. The Teen Room has its own Tech Suite with a green screen, Smart Board technology, and video and camera gear.
History fans should head for the Delaware Room. It holds archival documents, and a fireplace adds a homey touch to the building.
Step outside and the fun keeps going. The library sits on a 10-acre cultural campus with the Lewes History Museum, an outdoor concert stage, the Children’s Learning Garden, and Stango Park.
Got a bike? The campus also serves as a hub for an 18-mile regional hiking and biking trail.
You can borrow Chromebooks and WiFi hotspots, too. Programs range from book clubs to a Spanish conversation group and art exhibits.
Fun fact: library history in Lewes goes back to 1702. That’s a long time to be lending stories.
Address: 111 Adams Ave, Lewes, DE 19958
2. Rehoboth Beach Public Library

A crab named Clawdia serves as the official mascot here, which feels exactly right for a beach town. The library sits on Rehoboth Avenue in downtown Rehoboth Beach.
Its roots run deep. The Village Improvement Association started it in 1912, and the first collection lived in a member’s living room.
Later, the library spent 43 years at City Hall. It moved to its current spot in 1985, and an east end addition followed in 2000.
Need to get grown-up stuff done on vacation? You’ll find printing, copying, fax, scanning, and notary services, plus free Wi-Fi that reaches the parking lot.
Kids can join Read to a Dog programs, which sound like the sweetest homework ever. Adults can try film programs, virtual yoga, or the Spinning Yarns craft group.
Parking in a beach town can test your patience. Library users get free parking, and summer visitors staying over 30 minutes can get a daily parking pass.
Renovations are underway, so the meeting rooms are offline for now. Those spaces are expected back in Fall 2026.
Can’t make it in? The Homebound Books program brings reading to patrons who can’t visit.
Address: 226 Rehoboth Ave, Rehoboth Beach, DE 19971
3. Dover Public Library

Need a passport before a big trip? The library in the capital city is an authorized Passport Acceptance Facility, which makes it far more useful than you’d guess.
The current 48,000-square-foot building opened in September 2012. It serves as the anchor library for Kent County.
Its history earns bragging rights. The library began as a private subscription library in 1885 and became Delaware’s first tax-supported public library in 1902.
The building is pretty clever, too. Geothermal heating and cooling, solar panels, and a rain garden on the second-floor roof help it run greener.
Inside, teens claim the Teen Loft. You’ll also find a cyber café, a gallery, an auditorium, and an outdoor performing area.
Music lovers can catch the In Harmony Concert Series. Tech beginners can try Quick Bytes digital literacy classes.
A private teleservices space works for job interviews or telehealth visits. The Library of Things lets you borrow items that aren’t books.
Gardeners get perks as well. A seasonal seed library helps your backyard grow for free.
The fun even leaves the building. A StoryWalk at Silver Lake Park and Little Free Libraries in local parks spread reading around town.
Address: 35 Loockerman Plaza, Dover, DE 19901
4. Georgetown Public Library

Sussex County’s seat of government has a library that keeps things refreshingly simple. It focuses on the basics people actually use.
Little ones can enjoy storytimes. Grown-ups can sign up for classes, which is a smart way to learn something new without paying tuition.
Computers are ready when your home setup lets you down. That matters for job applications, school forms, or a laptop that picked the worst day to quit.
Quiet rooms are another big perk. You can study, read, or focus on a project without background noise from a busy house.
Parking won’t stress you out. The library offers a free lot plus free street parking nearby.
Timing your visit helps. Wednesdays tend to be the busiest day, along with Saturday mornings.
Weeknight hours run until 7 PM Monday through Thursday. That leaves time for a stop after work or school.
Saturday hours are shorter, wrapping up at 2 PM. Plan accordingly if your weekend errands run long.
Not every great find needs fireworks. Sometimes a quiet room and a free storytime are the discovery your week needed.
Address: 123 W Pine St, Georgetown, DE 19947
5. South Coastal Library

Pen pals in Ireland and New Zealand? Yep, this Bethany Beach library takes part in international pen pal programs.
A library first opened on Garfield Parkway in 1978, replacing a bookmobile stop. The Kent Avenue building opened in 1994 and reopened after an expansion on April 20, 2009.
Today the building runs about 22,000 square feet. Kids get a dedicated children’s room, and teens get a lounge with games, graphic novels, and computers.
Step outside to the Reading Garden. It has benches, tables, and Wi-Fi, so your email can come along for some fresh air.
Family tree detectives, take note. Ancestry Library Edition is available on public computers, and one-on-one genealogy help is offered.
The program list is wonderfully mixed. You’ll see concerts, history lectures, yoga classes, kids’ science activities, and adult crafting workshops.
Writers can join FreeWrites sessions with the Rehoboth Beach Writers Guild. Book clubs also meet, including a true crime discussion group.
Free public Wi-Fi doesn’t even require a card. Cardholders also get Freegal Music+ access for streaming tunes.
Address: 43 Kent Ave, Bethany Beach, DE 19930
6. Laurel Public Library

Down in western Sussex County, Laurel keeps a public library ready for readers of any age. Its collection covers materials for adults and children alike.
A private room is one of its handiest features. Picture a quiet study session, a focused work call, or simply a place to hear yourself think.
Families can make this an easy shared outing. Kids can pick their books while grown-ups find their own next read.
Borrowing is free with a library card. That means you can test-drive a new author without opening your wallet.
You’ll find it on East 4th Street in town. It makes an easy stop between other errands.
Want a calmer visit? Wednesday evening tends to be the quietest time of the week.
Mondays and Thursdays draw bigger crowds during the day. Hours stretch to 7 PM Monday through Thursday.
Fridays close at 5 PM, and Saturdays wrap up at 2 PM. Sundays are closed, so save your Sunday for reading what you borrowed.
Small towns don’t always get flashy headlines. A free library with a private room and shelves for the whole family is still a solid win.
Address: 101 E 4th St, Laurel, DE 19956
7. Harrington Public Library

Rural libraries often pull double duty, and this one serves more than one town. It supports the City of Harrington and nearby communities, including the Lake Forest School District.
That’s a big job for a Kent County library. Students, parents, and neighbors from beyond city limits share the same free resource.
Families will appreciate the practical touches. Kid-friendly activities are offered, and changing tables are available for parents with babies.
A gender-neutral restroom is also on site. Small details like that help more people feel comfortable stopping in.
Parking is simple and free. You can use the lot or grab a spot on the street.
Hours here have a clever rhythm. Tuesdays and Thursdays run from 11 AM to 6:30 PM, giving late risers and after-work visitors a shot.
Mondays, Wednesdays, and Fridays open at 9 AM. Saturday hours are short, from 10 AM to 1:30 PM.
Want elbow room? Tuesday and Thursday mornings and evenings tend to be quiet.
Wednesday and Saturday mornings get busier. Plan around those if you prefer a calmer visit.
Address: 101 Little Mastens Corner Rd, Harrington, DE 19952
8. Appoquinimink Library

Laser cutters at the library? Middletown’s newest library has them, along with 3D printers and computerized vinyl cutters in its Maker Space.
The building opened in 2022 with an open layout and 30-foot vaulted ceilings. That’s a lot of headroom for big ideas.
Aspiring video makers and podcasters should look here first. A video production studio, recording studio, and media lab were a first for a Delaware library system.
Little kids get interactive play areas and a spark wall to explore. Teens have their own dedicated area.
The green credentials are impressive. The building is LEED-Silver certified, with rooftop solar panels, LED lighting, and car charging stations.
Even the landscaping takes it easy. Native meadow plants need no irrigation.
Groups can use a community room that seats up to 115 people. Programs have included coding workshops and genealogy research nights.
Library history in Middletown dates to 1901. The Middletown New Century Club started it as a grassroots effort.
Check hours before you go, since the branch closes on Thursdays. Sundays run from 1 to 5 PM.
Address: 204 E Main St, Middletown, DE 19709
9. Route 9 Library & Innovation Center

A big tree where locals once gathered inspired the design of this New Castle library. Its perforated metal exterior filters sunlight, a little like leaves overhead.
The 44,000-square-foot center was completed in 2017. It was built to help revitalize the Route 9 Corridor community.
The sensory room deserves the spotlight. Developed with Autism Delaware, it lets visitors adjust sensory stimulation and was noted as the first of its kind in a U.S. public library.
Creative types can lose track of time here. There’s a Maker Lab, a STEM Lab, a Media Production Studio, and a LEGO room.
Writers get a space called the Scriptorium. Performers get a black box performance space.
Curious about cooking? A teaching kitchen is on site, and an outdoor farmer’s market adds another reason to visit.
You can pick up skills like video editing, animation, and robotics. Public computers, meeting rooms, and study rooms cover the everyday needs.
And yes, there’s something called a Bookatarium. The name alone earns a visit.
Thursdays are closed, and Friday hours end at 1 PM. Sunday afternoons tend to be the quietest.
Address: 3022 New Castle Ave, New Castle, DE 19720
10. Wilmington Public Library

Rodney Square sits in the heart of downtown Wilmington, and the city’s public library holds a spot right there. That makes it an easy add-on to a downtown errand run.
Quiet is the name of the game. It’s known as a calm public library, which feels like a gift in a busy city center.
Computer resources are extensive. Need to job hunt, finish homework, or fill out an online form?
This is a solid place to do it.
Community programming rounds things out. Check the calendar before you go, since events give you another reason to linger.
Parking takes a little strategy downtown. Free street parking is available, along with paid street spots.
Hours run 9 a.m.–7 p.m. Monday through Wednesday, 9 a.m.–5 p.m.
Thursday through Saturday, and Sundays are closed.
Hoping to avoid a crowd? Monday and Wednesday daytime hours tend to be busy, so Thursdays may be a calmer bet.
Wilmington is Delaware’s largest city, so a free, quiet room with good computers is valuable. Downtown doesn’t hand out many freebies.
Libraries like this prove a great discovery can cost exactly zero. Your library card might be the best deal in your wallet.
Address: 10 E 10th St, Wilmington, DE 19801
