I just had a look on the website. It would appear you get two books but when you look closely at the image the map on the book front cover is for all of Europe.
It also looks like the website is not yet updated with next years availability periods and prices

Mine has also turned up. I'm getting old wish the print size was bigger.

Edit for those who do not know what ACSI is all about:-
ACSI is a discount scheme you buy into, run by a company in NL. Typically for about £12/15 a year you get a couple of books on participating sites and an option on an app. The deals are available for out of high season camping and cover your unit, electricity, showers etc.
I bought into ACSI when I retired and whilst I agree it does not always offer the best deals, you have to do a lot of digging to get better.
Even though we now caravan out of high season I've carried on my habit of booking first and last campsites of a European break for peace of mind. Booking a long way in advance I've found the C&MC often match or just beat ACSI rates, but it is a close thing and you have to do a lot of number crunching.
Joining ACSI really is a no brainer though. Our Europe 2 trip will see us in Carnac from 26th August for 6 nights. This is on the cusp of ACSI availability and limited available pitches for what will still be high season for the Brits. Even after a greedy booking fee those 6 nights will be Euro 80 cheaper with ACSI. As I said a no brainer.
