I'm sorry to tell you that this recurrent argument is wrong!
ASN.1 is a joint standard between ISO and ITU-T. And everybody has the
opportunity to freely download 3 ITU-T Recommendations from the ITU-T website.
Check "I wish to REGISTER in order to download up to three (3) Recommendations
free of charge" at: http://ecs.itu.ch/cgi-bin/ebookshop
and then download the X.680 and X.690 series.

True (there are even books on ASN.1 who are freely available, as well as
the ASN.1 standards, as I already mentioned).
But be careful and don't trust any URL on the web!
