Taking books in public domain and republishing them - this company practices unethical selling by not filtering search results on other web sites by defining in search settings up front that they are selling reprints. In other words if you enter that you want a book originally published in 1915 and not a reprint - their reprint will show up in the results even though it is POD. They do little to correct this. You can literally get anything they are selling for free on ***** or ***** or Hathi trust, Another parasite selling something you can get for free and exploiting the great writings of Western Civilization..
