Where are the Welsh research tools?

I've been looking at records available at the Gwent County Archives to determine exactly what is available from FamilySearch and what is not. There are some nonconformist chapel records which are not listed in other resources. There seems to be no single place to go for a complete list of chapel records. The particular chapel I was investigating has some records deposited but the most used reference book, Nonconformist Registers of Wales does not list the available records. Since that book was published nearly fourteen years ago it could just be too far out of date. Tomorrow I will dig into it a little more and see if this particular chapel is just an odd ball or a good example of how to hunt and find Welsh chapel records.
