This particular set of Harry Potter books is very good. First off, it has The Philosopher's Stone, not The Sorcerer's Stone. All the books are in perfect condition with amazing art on both the front and back of all 7 books. It is exactly the same as any other copy of Harry Potter you will find, if you were to compare these books with ones from 2007, you would find no difference in any of the wording. One thing that sets this set apart from any other is that parts where a character is reading a leaflet or letter is depicted with a special font or some sort of symbol to make it look like the character is reading it. (I'm not sure if this is the norm now, my previous set of HP books was quite old) An example of this is when Harry finds blood writing on the wall, the text is written in a front as if it was blood that has dripped downwards a bit. In the older books however, the text simply would have been separated from the main paragraph and made bold. The words are well spaced out, making some of the books thicker than my old set and some thinner. Again though, they are identical in terms of words, down to the last character. Overall, a fantastic series made even better by a great set of quality, cheap books.
