At Villanova, we have largely tried to eliminate catalog links for things that are not full text – i.e. we did some bulk search/replace to eliminate table of contents links from our catalog, as we felt that these caused confusion and offered minimal value. I wasn’t directly involved in the cleanup, but I think this was done by pattern-matching, as these were mostly LOC-hosted links.
When it comes to linking to full text in MARC records, we generally favor one link over many links – it makes record maintenance that much easier.
Regarding display of 856 fields in VuFind, this will become a little more flexible in release 1.4 (due next month… and I can show you how to patch the improvements into earlier versions if necessary). The new functionality will display subfield y as the text if available, failing over to z if y is missing. It never uses x, since that is designated non-public, but this behavior could be easily customized if necessary.
We’ve been discussing the best way to handle 856 links for different situations, and would like to hear about your practices
1. Do you treat the display of links to a full text version differently from supplemental links, for things like Tables of Contents and Summaries? If so, what do you use to identify full text and supplemental links? We’re looking at the criteria in http://code.google.com/p/solrmarc/wiki/CustomIndexingRoutines for getFullTextUrls and getSupplUrls, which uses the 2nd indicator and text from subfields 3 and z to make the determination. Does anyone use different criteria?
2. For multi-part series and serial, do you have a separate link for each issue, or one link for the entire series or journal? If you do some of both, what’s the deciding factor?
3. Do you pull the descriptive text for the link from one of the subfields, like x or z? Is there a preference which subfield is used?
