Psst. SRU/SRW are not necessarily designed to return holdings.
Instead, they are protocols designed to interface with indexes. Send
a query. Return a list of hits. Using SRU/SRW to return holdings
would be a novel use of the protocol; using SRU/SRW for this purpose
would be akin to using something like OpenSearch for this purpose.

Eric, isn't the "hit" usually a record? And doesn't the record in the
library catalog represent at least one "holding"? And aren't there often
holdings fields included in the returned hit?
The projects that Janifer mentioned respond to the fact that our exchange
of detailed holdings data (especially for serials) hasn't been very good,
but I'm sure that I've been around link resolvers that are at least 5 years
old that would take data from an article in an A&I database (even before
the OpenURL), look up the ISSN in the catalog using Z39.50, and parse out
holdings to let you know if, more or less, your library holds that in hard
copy.
Are we talking about the same thing here?
