To assist you with any part of your homeschool journey (and to make sure I never lose them, either) these are many useful links we have used. Quite a few are curriculum companies. While we have not ordered from most of them, and I may not agree with all of their curriculum, I have often found their literature and reading lists to be helpful in finding what I am looking for.
I am sure there are many more out there yet to be discovered and even many more I will never find. For now, these have been useful in some capacity to us.
