I was looking for Precalculus ebooks/notes and I have found the following links. Most of these books are are licensed under Creative Commons and/or lecture notes so, I assume that they are safe to download.

As for 10, 11, and 12, the website containing the links may have obtained permission from the publisher to display it online, but I don’t think it is legal to download them.
