A django based system that provides a stable URL for every item in the library's catalog. Various discovery services will link to these URLs. The page for each item will in turn link out to various other resources that provide methods for accessing the content of the items.
This happens regularly. An example stacktrace, on /isbn/041516947X. Note the u'aulast': [u'Pappe\u0301'] in the openurl querydict:
