It's a great little booklet that I have found if you are interested, at all, in learning various tunes on your Tin Whistle. It is:
The Tin Whistle Tin Book; Thirty-Eight Tunes Appropriate for Tin Whistle, Fife, Flute, or Violin.
It is compiled and arranged by: William E. White
It was printed in 1980 by The Colonial Williamsburg Foundation. I am in possession of the ninth printing, dated 1990. It was, of course, printed in the USA.
Its ISBN is: 0-87935-051-2 (79-26872) for those of you interested in ordering it. (The Colonial Williamsburg Foundation, Williamsburg, Virginia, USA, 23185)
Have fun!
