Parts catalogs

[Anton Gaidos III <anton_gaidos_iii@firepower.com>]

All,
 Which Audi catalogs are worth pursuing? I have found myself in a
position where I have many, many VW parts catalogs
and two VWs not needing parts and one Audi needing parts but no
catalogs. 
 I am soliciting opinions here about parts suppliers as well as names
and numbers of parts suppliers.
Thanks. In fact many thanks for the assistance I have received!
