June 16 - August 7* Tuesday - Friday, 12 - 1 pm Lunch is available for no-contact pickup on a first come, first served basis, while supplies last. There are no restrictions on family income. Since 2015, LA County Library has been offering free, nutritious lunches to kids 18 and under with its Lunch at the Library program. It keeps children and teens nourished during the summer months, helping to ensure that kids return to school in the fall ready to learn.

This program is supported by a grant from the California State Library. *Lunch will not be available at any locations on July 3.

It's a big library with lots of books, computers, old magazines, and up to date magazines. Very very huge place to study. Nice professional staff to help out too. It's a awesome place to study.

I'm a current student at Cal Poly and I always study here whenever I'm on campus. The library is…read morehuge and has six floors that students can study at or find research. In addition, study rooms are available but they have to be booked and reserved ahead of time. If you seek really quiet or near-isolated areas, the 5th and 6th floors are the places to go. Wi-Fi is complimentary in the library and I believe that you can also eat/drink inside. (Or at least that's what I do, haha). The amount and supply of library books and research materials are endless and superfluous. If you are a student who is looking into borrowing physical hard copies to support your research, I highly recommend the library. The library also has flexible and long hours that can stretch late into the night, which is perfect for those who are staying in to study.

The only downside was that my seat didn't have a table to go with the outlet, though that was totally my choice haha. It is on the smaller side, and you'll need to park in an underground garage and take the elevator up to reach it.

Came here with my best friend her son and baby girl after school to check out some new books to read together. I used to just buy books but got overwhelmed with so many that it's easier just to rent a book plus gives us a reason to read new ones together. All the employees are really friendly. My friend had to get a library card I already had one so checked out 3 books. Usually park underground the lot is always full but found handicap thank goodness near the elevators. Nice courtyard they do tree lighting near here too during Christmas time. It's a cute little area for the library. Return book time is 3 weeks which is nice. Thank you for your help in finding books and for your friendly smiles. Baby girl and I also found a puzzle on the table we were trying to do for a bit too. Love this library. Have a beautiful day, thank you for the beautiful books and friendliness. :) Aloha

You can print, but you must need to put money on your account beforehand via the Pharos system, which is located upstairs in the library. Do it ahead of time or else your S.O.L. if or when the library closes. 3. Food is not allowed, but meh, who cares? 4. Study long and hard!

I was told I can submit everything by going online to the citation processing website. There is no way to submit the appeal into that website it won't allow to upload videos that are 8 Seconds nor it won't allow you to upload the photos because once you upload the photos it gives you a new option to submit the appeal and it won't take it, when you click on submit it just gives you all these red asteriks where you have entered information and even tells you where you are entering the country where you are filing the complaint that United States is wrong !! Phone number, email address, ZIP code number, etc., et. , name, really ??? Even the name says is incorrect. it just looks like a christmas letter rather then an appeal form.
