A couple of lines from comments is also useful. As well as tags (see the current content server interface). But, more importantly, I meant having that information be visible without the need to hover over entries. Scanning over a list is a lot faster than having to hover over each item individually. This is particularly important in the scenario where you are displaying a small set of books, say the result of a search or if the user goes via a tag/series/author/etc.
Not to mention that you cannot hover on touch based interfaces.
