Good morning, All,
NPR program On the Media hosted a discussion on the differences in federal statutory ability in searching email and other information stored in a cloud environment over print or non-cloud digital environments. The Stored Information Act (about 25 years old) has been also used to support searching info that might be useful rather than to support an identified purpose.

Thanks,
Susan
