In the case of, for example, a photograph of a chart, we would be using 776s in both records to link those bibliographic records in our Koha catalog and in OCLC, since the photograph is, in a sense, a reproduction of the chart. It's the same way we link between digitized books and hardcopy books--they each have a 776 linking between them. We use the 856 $u for a link to the item itself--the item in that particular record. E.g. this is a record for a hardcopy bookplate with a 776 linking to the record for the online version: http://keys.bywatersolutions.com/cgi-bin/koha/opac-detail.pl?biblionumber=36264 And this is the record for the online, digitized, reproduction of that hardcopy bookplate which not only has the image loaded in our Koha catalog, but has an 856 to where the online version lives outside of the catalog (in our digital image repository, NPS Focus), and has a 776 linking it to the bib record for the hardcopy version: http://keys.bywatersolutions.com/cgi-bin/koha/opac-detail.pl?biblionumber=36289 If we had a photograph of the bookplate, the bib record for the photograph would have a 776 field in it referring to the record for the hardcopy, but no 776 to the online version since the photograph wouldn't have a relationship with the online version (this all gets rather abstract!). So, yes--the 776 is being used for "alternate/different" formats--"additional physical form"--such as hardcopy and digitial, original and reproduction. It doesn't "link," or contain a link, itself as in the sense/function of a hypertext link, but bibliographic systems such as Koha and OCLC can use the fields to generate links among all the different manifestations of a work. And we're not using 856s to link between bibliographic records, but to link to the item that is being cataloged/represented by that bibliographic record--it's "electronic location."
