Kindle New York Times Subscription

How to save newspaper subscriptions on your Kindle indefinitely?
My boss has a Kindle. He wants to be able to save his New York Times documents indefinitely. 'd Also like to choose certain questions of other documents for an unlimited amount of time. So far I can only find that auto saves for 7 days. Any ideas?
The Kindle store the seven most recent issues of their newspapers and magazines. To save a copy of an issue indefinitely, open the issue, press the Menu button, and select "Keep this issue" and will then the word "hold" on the left of the title of the item at home. The only way to store more than 7 tracks that would keep in a computer and manually move back then forward. It's just how the Kindle.
