Public Libraries have to beg local and state (mostly state) governments for funding. Most of the cool stuff your local library has added? Yeah that came from either grants or donations. The actual funding is fought for very hard every single day. The best thing you can do to support public libraries? 1) get a library card most importantly, 2) get involved and vote in local and state elections, 3) go utilize all the free stuff available at libraries so we keep getting money to continue having that cool stuff for you guys.
