I’m often asked for a list of art books that I think are valuable in a homeschooling library. I created a post years ago that is still relevant today: Art Books: My Suggestions for a Basic Library.
Take a look at the suggested books and see if you already own any of them. Then, make a list of books to check for at your public library. I always like to look at a book before I purchase it, saving precious homeschooling dollars.
Note there are the essential books that form the foundation of my art library listed in the archive post and then there are several other resources I highly recommend. Keep a wish list on Amazon if you don’t have the budget for new books yet.
Please note the links above are Amazon affiliate links to books I own and LOVE.
