When I write this, Regular Expressions Cookbook is at the top spot in Amazon.com’s computers & internet bestsellers, its first day in the top 100. Its overall sales rank among all books sold by Amazon.com is #117.

Hitparades like that are very volatile. A book like ours that’s focused on a particular technical subject won’t stay at the top very long. So you’ll have to forgive me for tooting my own horn a bit after sacrificing several months of my life on this. (The whole process took a year, but Steve and I didn’t work on it full time.)
