As this is a review for a Kindle book, I think the most important review is how easy it is to navigate.
The book actually contains the Declaration of Independence, the Articles of Confederation and the Constitution with amendments. The 'Independance' typo noted in a separate review appears to have been corrected and I did not find any occurrence of the misspelling when I searched for it.
From the Kindle menu, the 'Table of Contents' is not available. You can only go to the cover, beginning or a specific location.
When the book first opens, it goes to the first page of the Declaration of Independence. In my view, it should start on the cover or the contents page. There is a Table of Contents page and if you turn back one page from the Declaration, you come to the contents page.
On 'goto' the 'cover', it takes you to the Cover page. The Cover page is simply text listing the contents and the actual links for the Table of Contents are on the next page, which is fine. It seems to me that it would be more efficient to combine the Cover page and Table of Contents into a single page, but this is not the case.
On 'goto' the 'beginning', it takes you to the first page of the Declaration of Independence. This would probably be fine if the 'table of contents' link in the 'goto' section worked, but it doesn't, so there is no obvious way to get to the Table of Contents.
There are no further sub-links for the Declaration of Independence, which is workable as it is relatively short and has no subsections. Fortunately, both the Articles of Confederation and the Constitution each have links from the first page to each of the main sections in the respective document. Inside the document, there are no links forward or backward, so you simply use the page and 'back' keys to navigate each document.
There is no index or other facility to aid in searching content, other than the Kindle search function. The search facility appears to work for the few simple searches I tried, but I suspect that has more to do with the Kindle than the book.
It could be better, but for $0.99, it's not too bad.
On the document itself, my view is that an understanding, by every citizen, of the US Constitution and just how far the Federal government has strayed from it are pivotal to preserving the few freedoms we have left and regaining those we've already lost.
