    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.

    I love coming to the library any chance I get. I usually come here for some peace and quiet,…read moregetting some work done. This library in particular has a good amount of parking. The inside feels a lot bigger than what it seems, which I love! A few remarks is that not all tables have an outlet accessible and the wifi itself could be a little bit stronger. Other than that, a wonderful library to experience and support!

I realized the things I could do on the laptop was more than I can achieve on the cellphone. So I saved to buy me a used laptop, to find out I forgot how to use the laptop. I just needed the basic. No one had time for a senior with computer and cellphone issues at home. I decided to go to the library. They helped me. Even when they had employee change, the new one would take up where the one before left off. It just had one stiff neck. A female. The last one but she didn't spoil the day. There were to many before her that paved the way in beautiful light. Yes, LA County Library in Claremont is the best. At least to me.

I love that we don't have to worry as much about disturbing other older patrons who are here to enjoy the quiet as this section seems to appeal to younger guests. My favorite feature are the lovely green bench style seats for the kiddie computers. There are also a lot more workstations/computers than compared to the La. Verne and San Dimas libraries. The surrounding area can get quite busy on the weekends, but there is a parking lot for library visitors.

    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.

We came to his LA County Library to get my 5.5 year old son a library card! Staff was helpful and friendly. He was happy to see all the books and very large kids section. We didn't check out a book this trip, but my son and his sister played in the area with a few food toys and kitchen. We will come back to check out more books and bring some home, so my son can learn to read better. There's so many resources that the library provides and now that my son is in kindergarten, I'm sure we will be frequenting the library often. It's nice that there's a restroom in the kids area, which was clean. You can park on either side of the building, which is something I didn't see until we walked into the library. Thanks LA County and Diamond Bar for the excellent library! Xie Xie!
