Just a quick post to note that Regular Expressions Cookbook by Jan Goyvaerts and me (published by O'Reilly Media) is available for pre-order on Amazon.com, Amazon.co.uk, and many other places. It was mostly completed at the end of January, and is coming out May 15 June 4.
Regular Expressions Cookbook contains a full regex tutorial (presented in cookbook format) and over 100 additional regular expression recipes that are explained in depth and work with C#, Java, JavaScript, Perl, PHP, Python, Ruby, VB.NET, and more. Get it while it's hot!
And yes, that's a rat musk shrew (or more specifically, greater white-toothed shrew) on the cover.
