Answer:
d) shifted away from issuing paper copies of materials.
Step-by-step explanation:
United States have made most of the federal documents available in the internet and people can have access to it freely and publicly. Any important archives or documents of U.S. can be easily available by accessing the internet. Thus now the U.S. government have given away the process of providing paper copies or photo copies of the materials to the public and request them to access it from from the internet or can even download it.
Hence the correct option is (d).
