I do agree with you that the Journal should not take care of business
like searching through external repositories, in fact, IMHO, the
Journal should not do anything that makes it try to connect to the
Internet, or even a school server (a hard dependency on network should
be avoided as much as possible). However, given that, I think,
mimetype specific custom metadata support in Journal should give us a
reasonable way to manage books stored locally - and if no one else is
working on it right now, I can take a shot.

What I do not want to do at this stage is do the book management
inside Read itself (it is Read, and not Manage Books :-). A separate
activity is required for retrieving books from external sources, and I
think Get IA Books is a great start, and can be quickly extended to
support something like Feedbooks (though probably we need to consider
Feedbook's ToS at http://www.feedbooks.com/termsofuse before trying to
go ahead with the coding).

We may even want to support OPDS catalogs (compressed as well as
uncompressed) as journal objects, opened and browsable via Get IA
Books or its later form.

Thanks,
Sayamindu
