This volume is a bunch of articles about arranged marriage and various issues related to this (and marriage in general) literally copied and pasted off Wikipedia literally as is, with literally no clean-up of text or anything else. Literally. The text is very clunky since it was not cleaned up or formatted properly. You can see arrows where on Wikipedia there were links, as well as 'citation needed' and other html markup. Foreign language text along with symbols are also missing from the printed text in this book.
There's nothing with with Wikipedia itself. It's a lovely source of free information, but it needs to be taken with a grain of salt due to vandals and people posting - intentionally or not - inaccurate information. To exacerbate the problem, the original subject of this book actually only makes up part of this volume, so you get a lot of stuff that you don't need but still have to pay for. If you've read Wikipedia, you are familiar with how some words within the article provide links to other articles (for those curious and wishing to expand their research/reading) and while this can be helpful, not all of the links within any particular Wikipedia article are too relevant to the original subject matter. There is also often a list of other articles at the bottom of any Wikipedia article that are 'See also...' but these articles vary in relevance. Sadly, the 'editors' of this book simply click these links and copy and paste these articles, whether or not they're truly relevant (or even related) to the original subject matter.
The pictures within this book are also poor-quality, shrunk down from their original versions and made black-and-white. Diagrams and other technical images therefore become near impossible to read or study. The size of the actual book itself isn't very large, and is about the size of a larger-size paperback, and the text itself is actually hard to read on top of being poorly formatted (some pages actually have rather large gaps/blank spaces)
You're better off reading the original articles on Wikipedia (at absolutely no charge whatsoever, updates included!), and if you wish for longer and more relevant books on this particular subject, you can look right here on Amazon for books written and edited by people who are genuinely passionate, educated, and knowledgeable about the subject of marriage (arranged or not)
