I help maintain a website ( http://www.nzetc.org/ ) which publishes 
texts of reasonably broad interest (Nineteenth Century New Zealand 
novels, the Official New Zealand War Histories, a couple of literary 
journals, early New Zealand ethnography, etc). We publish to the web and 
as ePub (+PDF in cases where the layout or typography might be important).

Currently we have MARC records that point to the web version, for 
internal use, but we're looking at making a MARCXML file available for 
download by third parties (we anticipate public libraries and perhaps 
school libraries). We'd like to make the MARC records as useful as 
possible to as many people as possible.

I'm looking for specific recommendations of how to code references to 
ePubs in MARC for maximum compatibility with multiple cataloguing systems.

[For those looking at our current ePubs, we're also working to increment 
the version of the standard we use to make them compatible with iTunesU.]
