This link at the OCLC site explains the service. They will send records on a regular basis with pre-arranged configs for 856, 9xx fields, and a few others.

Could you please clarify? Does this mean that OCLC is managing serials holdings on a month to month basis, or are they just sending you records that you identify at prearranged intervals?

We have just put through a request for MARC records, which is an annual cost, so I believe this service is now available.
We use TDNet and our initial beta loads were great, so now we want to pick up with the regular MARC record loads so as not to lose ground on this effort.
