What resources have you found that are winners in your homes? I'm trying to slim down my huge stacks of books in anticipation of our move. Fortunately, I'll be able to download most classical literature (speed is my only real concern). And we'll have Internet access for some historical and science studies. But still, there is something about having books and materials to actually hold, use and explore.
So, in each area:
History (both US and world)
Religion (Bible, catechism, saints, etc.)
Dramatic Arts, Photography, Hobbies, etc.
... and anything else you have found your family comes back to again, and again. My kids' academic level is now only middle and high school age ranges.
I'm thinking more along the lines of items that aren't grade specific as much as useful for the long term. This will help me make some decisions about any "can't live without, can't get in Peru" supplies. The ultimate goal is to perhaps get the most bang for the mass and weight.
Please leave your suggestions for Yvonne in the combox.
