Aavso Variable Star Atlas
I am new to this forum, so please bear with me if I ask something that is clear to the others (tried to find it but couldn't).
There is this Aavso Variable Star Atlas, in my time (a while back ) that was a standard work for variable star observers. Now I do not find any reference to this atlas on the Aavso website, and when I do a search on Amazon I only get referred to used volumes in astronomical prices (> USD 700).
What happened to this nice piece of work? Has it been replaced by digital online resources? If yes, I must be getting old, I still like the good old paper copy.
Thanks for your explanations!
