Colloquial Polish by Boleslaw W. Mazur Colloquial Polish by Boleslaw Mazur. I read in a review, on Amazon UK, that the book and audio were very good and tried to purchase them. They were unavailable or second-hand copies sold for extortionate prices, especially from USA sellers. I purchased what I thought was the "Colloquial Polish - The complete Course for Beginners by Boleslaw Mazur" from a UK seller on Abe books. What I recieved was just the CD recordings from 2003 version of the book. Do not make the same mistake I did! Read the notes below: The audio files for the Colloqiual Polish course are available, as a FREE download, from the publishers website: http://www.routledgetextbooks.com/textbooks/colloquial/language/polish.php The latest version of the book is also available on the same page for £39.99 , however it is cheaper on amazon UK at £31.98 I hope this information helps.
