One thing that would also be helpful along these lines would be to have these bibliographic records available for import into a program like Endnote, using one of the industry standard export formats. This may also help overcome interoperability issues with Pages, which supports Endnote integration.

Steve: I didn't discuss any future plans in the blog post, but we're already cooking up some intuitive ways on how we may be able to do this type of thing in a future revision (plus some other stuff that you probably haven't thought to ask yet!). For now, you may want to experiment with creating a user tool for all your resources, then copy it to your final bibliography.
