Expose specific module content fields to views filter

Is there a way to extract/expose fields from a module (I am using the book review module) so that they can be used as fields/arguments in a view?

Basically the book review module has fields for author, ISBN, rating, publisher, etc and I would like to use those to create a view of my book reviews. I suppose that this request goes for any module that creates a content type of its own.

I know that this could be done by creating my own content type, but it is nice to use already prepared stuff.

Thanks,
