I too have a number of books with the IM imprint on board. Yes, sad to see them pull out of the market. I guess the market share and sales was not big enough for the corporate guys. But, these days thanks to electronic readers others can publish books themselves if they have a some modicum of skills. Though being able to find a page with that chart of info in a Charlie Wing or Nigal Calder book is certainly more convenient. That's why I carry them on board.
