Sheds cost an arm and a leg.

I am thinking digging a hole on my property to store certain
material underground. Do I need governmental permission to dig (I live
Oklahoma) half a garage size large and deep hole?

Some of the stuff that I want to store are lots of books and papers.
They could rott when I just put them in the ground, cover them with a
blanket and throw dirt over it. What material could I use to wrap
around to
protect the books and papers to protect the books and papers?

perhaps you can scan your documents and store the files on dvd's;
download the electronic version of the books and store them on dvd's.
where would the removed dirt all go? when it rains, the sidewalls
could collapse slowly or like a mudslide. although it is interesting
it could present a danger of collapse or drowning for anyone walking
onto the property, which is usually some variety of a criminal
negligence offense. depending on the climate, the underground storage
with its dampness and freezing/thawing could accelerate the damage to
your items.
