For certain purposes, yes, you organize data in records. But your
records must be designed such that the data can be used in other
contexts. Our records don't allow us to do this now. If we wish to do
linking and to take advantage of data on the Web that could be related
to our bibliographic data, then we must change how our data is stored.
Names could be freely floating, if properly identified with URIs. They
could float in our systems and they could float in a document on the Web.
I hate to invoke XML, but the analogy is there. With data organized in
XML, you can link to any node in the XML document or record. You can
link to the ISBN or to the publisher name or to the date of publication.
You can't link to our records today. And, no, just turning a library
record into XML isn't enough, so this is just for purposes of illustration.
