Just checked Amazon to see if I was correct about the 2d version perhaps being available there, but couldn't find it there -- just the first edition. Might want to read the reviews at Amazon for that edition. Quite a spread, with two reviewers giving the book 5 stars, one giving it three stars, and two giving it one star. I'd give it five stars, which breaks the tie.
I did find this info about a possible newer edition (2007) when I googled the author and title:
"This title is currently out of stock. A new edition is due in 2007. If you place an order, we will ship the item once it is available. You may cancel your order at any time, and your credit card will not be charged until the order is shipped."
In her 2d edition introduction, Woods welcomes "comments, suggestions, and recommendations" that can be sent to her at 1255 N. Iron Rock Road #6, Jackson, WY 83001.
Assuming that's still a good address after ten years (the invite is in the 1998 edition), you could always send Woods a letter asking if there has in fact been a newer edition since 1998, or if one is in the works, or at least whether the 2d edition is still available somewhere.
