Books: http://asn1.elibel.tm.fr/en/book/index.htm and
http://www.isi.salford.ac.uk//books/osi/osi.html to start with.
Website: http://asn1.elibel.tm.fr/en/introduction/index.htm is the
definitive, generally.
A CD-ROM / website with a nice open source ASN.1 toolkit and documentation
for same in DocBook, also published as an O'Reilly or similar, would be
nice - but I haven't got time, personally :-(

I see your 1986 and raise you two years! X.409 __1984__ and ISO 8824 /
8825 __1987__! And that's real ASN.1, ISO 8879 is SGML, which despite
being far more complex is but a pale shadow of XML+schemas; it was never
intended as a notation for data interchange, just documents... it's about
wrapping elements around text to "mark it up". In a structured, general,
way.
Stuff like groves seems to suggest that some people were having XML-like
ideas for SGML before XML came along, but it never took off; ASN.1 was a
data transport at heart since 1984 [not that it was called ASN.1 until
it became an ISO standard in 1987, though] :-)
