I am absolutely ashamed it took me this long to visit this gem within my beautiful city and encourage everyone to take advantage of this special space.

It is much larger on the inside than you'd realize, and they offer a ton of programming for guests of all ages. My daughter will be a regular visitor as she continues to grow. I am disappointed that this library does not participate in the Beanstack (1000 Books Before Kindergarten) Program, but that will not stop us from taking advantage of the massive selection of children books.

LA County Library - Diamond Bar Library *June 30th, 2026…read more*10:00am-5:00pm - Tuesday *4 Stars Environment: *Moderate Sized Parking Lot *Helpful Staff *Average Seating Available Went here with a friend to get some work done and overall had a good experience. The staff was very friendly, and the library was clean and well maintained. I was actually surprised by how busy it was for the summer, with people of all ages using the library throughout the day. My friend and I were hoping to use one of the private study rooms, but they were all booked. For anyone planning to go, you can reserve a study room up to one week in advance for a maximum of two hours per reservation. We were a little disappointed that we couldn't reserve a room until later in the afternoon, but luckily we arrived right when the library opened and were able to find a table. One thing I wish the library would consider is allowing walk-in use of reserved study rooms if the reservation becomes a no-show. The room we wanted sat empty for the first hour we were there, and it would have been nice if someone else could have used the space instead. Overall, it's a nice place to get work done with plenty of natural light and a good atmosphere, although I do wish the chairs were a little more comfortable for longer study sessions.

I originally discovered Diamond Bar Library while searching for a quieter place to study after…read morespending time at the West Covina Library. I still remember the first day I walked in here. The difference was immediate. The atmosphere felt calm, focused, and peaceful. It honestly felt like stepping into study heaven. For anyone who needs a consistently quiet environment to work or study, this has easily been one of the quietest libraries I've experienced in Los Angeles County. I spent many long hours here preparing for my medical board exams, so I really came to appreciate the environment. The layout offers a great mix of larger tables and individual study cubbies, and there are outlets available which makes settling in for long study sessions much easier. The library also feels very safe, likely because of its location next to City Hall and the fact that it sits a bit tucked away from the busiest parts of town. There are entrances in both the front and back, and I personally found the quieter seating area on the left side when entering from the back to be my favorite spot, especially the tables near the windows where you still get that nice natural light during the day. The staff has always been friendly and helpful as well. I believe one of the librarians named Jen really helped maintain a welcoming atmosphere. One thing I appreciate about this location is that they take maintaining a focused study environment seriously. For example, eating isn't allowed inside the library, which helps keep things clean and minimizes distractions. There is a garden area outside and you can always step outside for a quick snack break. After spending many hours here, I started to notice some of the daily rhythms of the building. The restrooms are impressively clean, which deserves a shout out to whoever keeps them maintained. The library also has a small bookstore run separately from the library itself, which is a fun little feature if you happen to stop by while it's open. If there were a few small improvements that could make an already great space even better, they would mostly relate to sound consistency. Because this is such a quiet library overall, small sounds can stand out more than they normally would. Occasionally conversations at the service desks or phones ringing can carry across the room, and sometimes outside maintenance work can be heard from the garden area. Nothing that ruins the experience, but little adjustments there could make an already peaceful environment even more ideal for studying. I also noticed that the closing announcements can be a bit startling if you're deep in concentration, so maybe a softer chime before the announcement could make it feel a bit smoother. Another thing that could help maintain the quiet atmosphere is occasionally reminding visitors with young children that certain sections are intended for quiet study. The kids' area is nicely separated, which already helps a lot, and a gentle reminder here and there would probably keep everything running smoothly. Overall, I'm genuinely grateful for this library. The long hours are fantastic. Being open until the evening made it possible for me to have full study days here when preparing for my boards. Yes, it was a bit of a drive from West Covina, but it was absolutely worth it for the calm environment and the ability to truly focus. Diamond Bar Library became one of my go to study spots, and it's a place I'll definitely remember fondly.

This was my first time visiting the Covina Library, and honestly, I'm conflicted because there are…read moreso many things done right here, yet one major issue overshadows the entire experience. As a Covina resident, I didn't even realize this library existed, since I usually go to West Covina, and more recently my favorite has been the Diamond Bar Library because of its overall standards and upkeep. From what I understand, this library is city owned rather than a county library, and unfortunately I think that's where the responsibility lies. The moment you walk in, the smell is overwhelming. Not subtle, not something you get used to after a few minutes, but truly unbearable. It honestly reminded me of walking into an abandoned home, which is shocking considering how lively and community focused the space actually is. I tried to push through it, hoping it would fade, but instead it gave me a headache, which was really disappointing. Layout wise, this library has so much potential. You walk in and there's a community area to the right, restrooms nearby that were clean but clearly very small and in need of updating, and a book section where you can purchase books, which is a nice touch. The librarians' main desk sits to the left, and the high ceilings immediately stand out in a good way. There's a children's section, computers in the center, and overall the space feels open. I was initially unsure where to go, but I was so grateful to find a designated reading room. That alone is a huge plus. Unlike West Covina, which can get quite loud, the librarians here do an excellent job maintaining a quiet and respectful environment. They whisper, they're attentive without being disruptive, and they clearly care about preserving the purpose of a library. There are plenty of outlets, and the reading room is thoughtfully placed so you're not constantly distracted by foot traffic or noise. What makes this even more frustrating is that this place could easily be a gem. The reading room has windows facing outside, so you still get natural light and that sense of being connected to the outdoors. There's even a patio area and a citrus tree right out front, which gives the space so much charm. The setup is fantastic, the staff is great, and the intention is there. It just desperately needs renovation. I truly believe more people would use this library if it felt more inviting. City of Covina, if you're reading this, please address the smell. Whether it's the carpet or something deeper, it needs attention. This library has so much going for it, and with some proper updates, it could easily become one of the best community spaces in the city. Unfortunately, this was my first and last time using the library. I hope the next time I visit is when it's a grand opening after renovations.

THIS IS NOT A QUIET LIBRARY…read more I've been holding off on writing this for a long time because I genuinely couldn't believe how consistently frustrating the experience has been. I come here often and stay for hours at a time to study. I'm not popping in briefly. I'm here working, focusing, and trying to use the space the way a library is traditionally meant to be used. I understand this is a public space funded by taxpayers and open to everyone. I respect that. But libraries also have rules for a reason, and here they are rarely enforced. That's the real issue. The open concept design might look modern, but it completely eliminates any sense of quiet. You can hear every front desk interaction across the floor. Phone calls, loud conversations, audio playing from devices, and people speaking at full volume are constant. Some librarians genuinely try to maintain order and I truly appreciate them. But others make no effort at all. Over time you start to recognize who will step in and who won't. I've had to get up and specifically find the staff members who will address disruptions. I should not have to do that. There is no dedicated quiet section. None. That alone is shocking. If you are looking for a peaceful study environment, this is not it. It feels more like a social space than a library. Food policies are inconsistently handled. I originally thought eating was allowed because everyone does it here, only to later learn at another county branch that food is not permitted. The rules technically apply here too, they're just not enforced. The same goes for phone use and strong odors, both of which are clearly addressed in library policies but frequently ignored in practice. The men's restroom also has a persistent odor issue. What makes this even more disappointing is that I've visited the Diamond Bar branch, which operates under the same county system, and the difference is night and day. The rules are upheld consistently and respectfully there. It's calm. You can study for hours without constant interruptions. That experience makes it clear that the issue here is not the public, but the lack of consistent enforcement and management. To be fair, there are positives. There are plenty of tables and outlets. The children's section is well designed and engaging. They offer programs for kids and adults, including community classes. The book sales are fantastic and affordable. And again, some librarians are helpful and professional. But the core function of a library should be to provide a space where people can read, study, and focus. When you cannot go more than 20 to 30 minutes without loud disruptions, that is a management problem. I'm not expecting perfection. Public spaces will never be silent. But basic rule enforcement is not too much to ask. If you want a quiet place to work, I strongly recommend going to the Diamond Bar location instead. The difference is immediate. It's disappointing that the library in my own city could be so much better with relatively simple changes. Consistency would fix most of this.
