Compilers: Principles, Techniques, and Tools 2nd By Alfred V. Aho (International Economy Edition) Paperback – January 1, 2007

Cheap material, but what do you expect from a cheap international version. Content is great, so 5/5.

The book came quickly. It had no damages. I'm looking forward to reading the updated version, as the last time I read it was many years ago in school.

The economic version is still a scam: hard to read because of the printing quality and there are random "ORIGINAL" stamps on the cover to hide the previous ownership. It is hilarious.

This book is not intended for sale in the United States. On the facing page to the TOC is this notice: "This edition is authorized for sale only in India, Bangladesh, Bhutan, Pakistan, Nepal, Sri Lanka, and the Maldives. Circulation of this edition outside of these territories is UNAUTHORIZED". There are also stickers on the front cover, top left and the back cover, bottom center, that might be hiding similar warnings. Both of these stickers just have "NEW" printed on them.Also from the back cover: "This international edition preserves the cutting-edge approach and pedagogy of the original, but may also feature alterations, customization and adaptation from the United States version."Follow-up ... I filed an inquiry with Amazon and heard from the seller and the sale is entirely legal following a Supreme Court decision back in the '90s. So much for the above. There are some physical defects, however, as some pages are not cut at the top and the text skews downward. Still readable.

Very nice book. Currently using for the compilers course.

Excellent book and a good reference book for all the future engineers!

As other reviewers have mentioned, this is the International Edition that's missing Chapter 12 and has other alterations. DO NOT BUY! I immediately had issues with the binding, pages just started falling out. The PDF for the US edition is available online for free. If you're like me and NEED a hardcopy, print it at your local Fedex.

If you thought you would save a few bucks buying the paperback be warned! The paperback is only in the "International" edition i.e. the version for India, Bangladesh et al. Just see the title of the book and it is already wrong! It is not authorized for the United States and states on the back that it may feature alterations et al. It is an unreliable edition that is unauthorized--not the true dragon book. I give it two stars because, besides the title, I am unable to find any other blatant issues yet, as this is the newest impression and the printers may very well finally be getting things right. Still, having an unreliable version makes everything more difficult, because what's the point of a book if you have to double check everything?
