I also agree to the point that we unfortunately have to deal with redundancies. 

But for the report IMO we should strictly differentiate between authority data and bibliographic data. I reckon we can suggest a centralization of authority data at least on national level. I assume a downsizing of bibliographic redundancies needs consolidated authority data and of course the consequent alignment of authorities in bibliographic entries. 

Without raising the FRBR discussion again, I think one of the redundancy reasons in bibliographic data is the lack of possibilities to link items with trustworthy bibliographic records. Everyone is creating own new bibliographic records - but this is also caused by the harvesting approach in current library environments and probably not changeable soon.

And a last point: for the identification and decrease of redundancies it's helpful to have standardized ontologies for the library community - maybe not only RDA but definitely not more than a handful...
