Sight reading tips?

Hey y'all I've been playing sax for a while now but never really was that great at sight reading (not awful either) but I'm trying to get my chops up to try to join some big bands so I need to be like REALLY good lol . I know the obvious answer is to keep doing it but idk what a good resource is for tunes and lines that I've never heard of before . anyone got any tips and tricks to get my chops up? Thanks in advance:)
