Regular Expressions Cookbook in PDF Format
O’Reilly’s website lists Regular Expressions Cookbook in PDF format for $31.99. That’s less than the list price of $44.99 for the print version, but just a bit more than the discounted price of $29.69 that Amazon.com is asking for the print version right now. But if you want instant access or you live in the tropics where it takes 3 weeks and costs $10 to receive anything from Amazon, and you don’t have a Safari subscription, the PDF is a good deal.
