This is the 19th edition of McNae's, and it doesn't take long to see why. It's updated in response to changes in legislation, and if you rely on having an accurate understanding of the law for journalism, it will almost certainly pay to stay up to date.
This is a set book for journalists doing NCTJs, and, from our point of view, an essential reference in our PR department -- alongside the Press Complaints Commission code poster up on the wall.
Journalism and the law are two things on which many people have opinions. There are lots of people who will quite happily say in a meeting "it's against the law to...", "newspapers are required by law to...", "they won't be allowed to print...". Unfortunately, a lot of this 'knowledge' is second or third hand, and much of it dates back to legislation or cases that have now been superseded. A lot of the rest of it is gleaned from conversations in pubs, and articles in newspapers. In other words, of very little value.
This book is the antidote: updated from the most recent changes and the most recent cases, and adopting exactly the right tone when it comes to describing things which are subject to being tested in the courts. And it's an awful lot cheaper than ringing up a lawyer.
Strongly recommended for anyone who actually needs to know.
