Want to see more? One way is to show your search results in 'cover view', which you can do by clicking on the "Cover view" link on the upper right-hand side of the page. For example, see what turns up when you search for plants or Holmes.

We hope this brightens up your search experience on Google Books and helps you discover even more titles on our site.
