Actually, the thing I really like about SCOP is that large parts of it
are the result of manual, expert classification by Alexei Murzin and
Cyrus Chothia. Many of the problems inherent in fully automated
classification schemes have been avoided. The partial automation
that's used is done to reduce the number of structures that Alexei has
to look at by eye -- detecting the obvious homologues, etc.

The SCOP reference is JMB 247:536-540, 1995. In the US, the SCOP mirror
site at PDB is

(Obligatory caveat: I'm biased; I'm a peripheral collaborator on the
SCOP project.)
