I would take a look at schoolbell, if I were you, and see how they do
it.  Schoolbell is a calendar application.  A calendar contains
events.  The calendar can be viewed by day, week, or month eg
http://localhost/calendar/2005-08-26 or
http://localhost/calendar/2005-w31.  The same events are shown in the
different views, but the event is a single object.

I think you want to create your own container type to hold your
objects.  This container's __getitem__ can do whatever you want in
order to find the book, in the example above, when asked for either
name.
