Query: Kindle version is broken - get the paper book

The Sears' writing style depends heavily on bullet points, lists, and sidebars, but the formatting does not properly come through in the Kindle edition. For example, a bulleted list in the book comes across as a run-on unpunctuated sentence on Kindle. Also, since the 300+ book only has a table of contents and not an index, it is difficult to navigate on Kindle. Searching is completely useless, as common terms are used hundreds of times throughout the book -- it's sad to say, but flipping through physical pages is more efficient.If you want to buy this book, read it cover-to-cover, and put it away, then the Kindle edition may be OK for you. But, if you want to use it as a reference, buy the book, not the Kindle edition.
