Karen, we're experimenting with a somewhat different approach here at
San Marcos, inspired in large part by the work Rolf Kwakkelaar has done
at Elsevier with "image-based linking."

Rather than send requests to SFX in advance of displaying search
results, we're displaying the results first (so they load quickly), and
then using the browser's inherent asynchronous loading of images to load
in a full-text or non-full text image based on a query of our SFX
Knowledgebase -- unless, that is, the database itself has native
full-text, in which case this processes is skipped.

Also, rather then query SFX directly for availability, we're downloading
a slimmed down set of information out of the SFX Knowledgebase, storing
that info in a local Oracle database, and querying that (and caching
results in memory).  That loads much, much faster than trying to resolve
a full OpenURL against the SFX API, and also keeps our SFX server from
getting swamped with requests.
