This Kindle edition is a no-frill version of the book, but is acceptable. It is the translation by William Ellis that was originally published in 1912. There is no table of contents or footnotes in this book, but there is an index that is not hyper-linked. With the format and content of this book, I saw no need for these features, especially since one could easily do a search for the desired locations for references.
The work itself is very interesting. I had read Aristotle's Ethics not too long ago and recognized his distinctive style of categorizing things in very logical ways. I would recommend reading Plato's works on politics prior to reading this book since the author spends a lot of time critiquing his works. He also refers to a lot of historical figures, so a good background in Greek history may be useful, though not necessary.
I found his descriptions of governments to fit well with small city-states as were common in ancient Greece. He did not go into a lot of detail on how to adapt these governments to the scale we are used to today.
Overall, this book is a good read for anyone interested in politics. Several principles he covers are valid today and one can learn much from his thoughts. One must read it with the understanding that he lived in a totally different world where slavery was acceptable and universal suffrage was considered dangerous. Therefore his definition of a democracy varies quite a bit from the modern definition. I'm also surprised by how much he feels government should get involved in peoples lives, including what and how to teach children and determine for them which career they should be in. Shades of Plato, though not as extreme.
