I wanted to find the answer to a very simple question: if I spend, say, $10,000 on an ebook library over a span of years, can I will that library to another party upon my death, as I can will my collection of printed books? For Amazon, the answer is no.
Use of Digital Content. Upon your payment of the applicable fees set by Amazon, Amazon grants you the non-exclusive right to keep a permanent copy of the applicable Digital Content and to view, use, and display such Digital Content an unlimited number of times, solely on the Device or as authorized by Amazon as part of the Service and solely for your personal, non-commercial use. Digital Content will be deemed licensed to you by Amazon under this Agreement unless otherwise expressly provided by Amazon.
Restrictions. Unless specifically indicated otherwise, you may not sell, rent, lease, distribute, broadcast, sublicense or otherwise assign any rights to the Digital Content or any portion of it to any third party, and you may not remove any proprietary notices or labels on the Digital Content. In addition, you may not, and you will not encourage, assist or authorize any other person to, bypass, modify, defeat or circumvent security features that protect the Digital Content.
In other words, Amazon does not sell ebooks. It licenses them. That means if you spend $10,000 on a library of printed books, that collection becomes an asset that can be resold or willed. If you spend $10,000 on a Kindle library, the value of that expenditure is utterly destroyed upon your death, and the library cannot be transferred to any other party.
And that completely sucks.
