missing libraries

Hi guys, I'm new to CI so please make allowances :o)
I keep seeing references to  CI libraries, but I can't find any. I've used Composer to install CI CRUDapp to get me started quickly and it's worked very well so far. I'm trying to port and old wordpress site of mine as a way getting to know CI.
I was looking to see what libraries were available that might save me a lot of coding but can't find any. The Libraries folder only contains the 3 files required by the CRUDapp to operate.
Is there a repository for all the libraries?
Thanks for any help

The CI 4 Libraries are in system

Thanks InsiteFX, it appears that CRUDapp doesn't include the system folder. So I used composer to install starterapp and the sytem folder installed with it. Thanks again, you're a time saver :o)

Your Welcome.
