Hallfiry's CD Index The catalog is currently switched off. It will be available again some time in 2017 or 2018.

Update Aug 10 2017: A mirror of the catalog is kindly provided by IllidanS4 over here:

Update Jan 25 2018: The mirror is not functional anymore. I will again try to get the catalog running, but I can't tell how long it will take. Maybe it'll happen still within 2018.
