another step in linking library records would be to supply a mapping
between individual records and the corresponding subject or
classification scheme, e.g. with ISBN or something like Bibkey
(http://www.gbv.de/wikis/cls/Bibliographic_Hash_Key). There are quite
a lot of schemes out there and not every scheme is used in a
particular library catalogue, e.g. we don't use LCSH. On the other
hand offering a user to browse local records with one or more
(external) schemes like LCSH would be desirable.
One possible solution would be to implement corresponding WebServices
that get a ISBN or Bibkey and then deliver the appropriate LCSH or any
other kind of related meta data. In my opinion a much better solution
would be to offer the mapping data as a feed of flat files like
LibraryThing (http://www.librarything.com/feeds/), e.g.
...
<mapping>
<isbn>123<isbn>
<lcsh>aaa</lcsh>
<lcsh>bbb</lcsh>
</mapping>
<mapping>
<isbn>456<isbn>
<isbn>678<isbn>
<bibkey>ea24ad</bibkey>
<lcsh>ccc</lcsh>
<lcsh>bbb</lcsh>
<ddc>345.223.444</ddc>
<bk>12.34</bk>
<osc>xyz</osc>
<rvk>yyy</rvk>
</mapping>
...
In this way only the relevant meta-data to link records is exposed and
not the entire MAB/MARC/whatever record - in case that might be a
problem. Then, with this data it would be possible to link indiviual
records in your own catalogue as long as the amount of 'feed-data' is
big enough and covers most of the local catalogue. Therefore this
would be easiest when the data comes from huge union catalogues like
LoC, LibraryThing or hbz, GBV, BVB etc in germany.
Is LoC perhaps already thinking in this direction?
We implemented this kind of browsing (called a classification browser)
through external classification schemes in our collective catalogue of
our university (KUG, http://kug.ub.uni-koeln.de/). All the institutes
in their more than 130 separate catalogues don't use the
classification scheme BK (=basic classification) in their records.
Instead the BK-data is merged as 'virtual categories' in the record,
so it can be used like any other browsable category in it. The BK-data
is provided by the university's large Central Library and collected
with several other enrichment data in a central enrichment database.

Oliver
