Your local public libraries can be a great resource if we don't seem to have exactly what you are looking for.
If you are a resident of the City of Los Angeles, you are eligible for an instant Los Angeles Public Library e-Card that allows access to all of LAPL's digital resources, including ebooks, audiobooks, research databases, and online tutoring. To sign up for a physical library card, you can fill out an application in person at any LAPL location. Learn about LAPL's borrower services here, and visit one of LAPL's library branches to sign up for a library card and gain in-person resources.
Outside of the city limits? Try LA County Library! They also offer e-cards with lots of great free resources for books, movies, and database access.
