I agree this might be in another thread, my mind was just to say that there are good advices in the book but there aren't always used by good herpers.
And even if handling a reptile or an amphibian is forbidden here in France, I'm pretty sure that almost nobody will ever be fined for that.
However, I can't give more details here as I didn't discuss that much about that, but for those who went to Mt Ventoux to spot V.ursinii, you may know that the high number of herpers manipulating a low number of vipers (as the population is really short-term endangered) may be one of the first cause of the viper's decline. Not that it's the only one, but it's having a very bad incidence on the conservation efforts (some people manipulate pregnant vipers and most of them abort).
Here's why these advices aren't suitables everywhere even if they generally are. But you said it in your answer.
For those who want the hardcover version, you can order it on Amazon (France for me, they call this "relié"):
