From time to time I search for the words like "tambon" not only in Google, but also in Amazon, especially in case their search inside books might return something Google Books does not have yet. That way I stumbled upon a book titled "Subdivisions of Thailand: Monthon, Provinces of Thailand, Amphoe, Administrative Divisions of Thailand, Thesaban, Tambon, Boriwen, Sukhaphiban", which looked like it have exactly the content I am interested about. But when reading the description in more detail I noticed that this book is nothing else but the Wikipedia articles from the category Subdivisions of Thailand printed. Looking around more, there are thousands of similar books from the same publisher with different sets of Wikipedia articles placed together, each printed individually as a Print on Demand book, but each having a unique ISBN number already.
Now this is all perfectly legal, provided that they follow the license of Wikipedia and cite the source correctly. And even though I have written the articles within that specific book myself to a great deal, I don't recommend anyone to buy this book - first I know that the Wikipedia articles are way from complete, there are still lots of points I would love to add if only I could get them researched well enough. When you order the book, you also have no control on which version of the article will be used, most probably the current one, but how to be sure that that version is clear from any vandalism? Also, the price of about 15 US$ for just 52 pages is IMHO way overpriced, especially as not a single cent goes to the author unlike it would in any normal authored or edited book, the only cost they have is the pure printing and shipping.
reproduced the same contents as the above cited book, which would cost you just 8.90 US$ - and can also alternatively be downloaded as a PDF to print yourself or put in your eBook reader. Too bad that this book won't become a bestseller for sure - even if I would get the six dollar price difference I won't become rich.
