Talk:ACM Computing Classification System

Sufficiently excerpted to avoid copyvio?

I expanded this entry to cover the top two levels of the system (previously, it had a list of all top-level topics and some but not all lower levels expanded). I deliberately cut off the description of the system to avoid describing lower levels in detail, except for one sample longer path, and in addition made some other omissions (the .0 and .m topics, and the cross-references from one topic to another) in the hope that this level of excerpting is sufficient for this to be fair use for review purposes rather than copyvio. But I'd welcome other opinions on that matter.
