Huh? On the library book interface, rather than a drop down list of a couple of simple premade sorts, you'd require a horizontal line at top of about three list boxes, drop downs or buttons to select the sort hierarchies from existing choices like: Genre, Title, Author, Publisher, Shelf, Series, Recently Read, etc., other choices could be pulled from metadata.

Selecting: Genre, Author, Title, from left to right in the new drop downs would yield a list sorted by Genres, within that by Authors and within each Author by Titles A-Z... which would be most peoples's hierarchy if they created a directory/file based hierarchy. If you could not still find your book by title in a sort you drilled down through, you'd then hit a search button, select either a metadata tag to search for or enter a phrase to search from the default book summary metadata field. The advantage is you could quickly narrow down the scope of the search by selecting the level at which you want it performed rather than searching the entire database.

Better yet, forgot the Author, no sweat set the top list sort parameters to Genre then Title and look at every Title A-Z in a certain Genre. Again narrow it further with the Metadata field Search if you can't find it by looking at the Titles for the Genre alone.

Just a simple idea, based on how people usually look for things while leveraging the computer to do the heavy lifting. By narrowing the search you speed things up considerably.
