Was given this book a couple days ago and it says it is the "second edition". This obviously means there must have been a first, so my question is how many additional editions have been published? Thanks.
You've got the best edition in terms of instructional value. The first edition was full of errors, which caused it to include a corrections or errata sheet. I don't believe there were any other editions published. Robin wanted to, but he reportedly couldn't get the publishing rights.
