Thanks for the $3 Amazon reference. I only have one copy of my (very) old book, and just ordered a used copy so I have a spare. I was surprised to see that Springer Verlag still sells it new - I thought that it was out of print a long time ago.

Certainly not my book :-)

Edi's upcoming book on Amazon is listed as $56, due December 2015. I will probably buy a copy when it ships.

EDIT: I just pre ordered a copy on Amazon to lock in that price.

The Erlang book direct from publisher has to be one of the highest ebook prices I've ever seen.
