No technical book ever written in error free. It just does not happen. You can look in the forum "Mock exam errata". They also discuss errata in books.

The M & R book does not have a reputation for having problems with errors, though as was mentioned, it will certainly have some like all technical books. Marcus
Even though the latest edition will be the cleanest, the site http://www.ii.uib.no/~khalid/pgjc/jcbook/errata.html has errata listed for each edition separately. So whatever edition you get, you can be brought up to the latest version's standard by reading through the errata.
See the link I posted above. At the bottom of the page, it describes how to find what edition your copy is. It can be a little confusing, so good luck.
