The Library Bookshelves plugin allows you to curate virtual bookshelves just like you would a shelf around a theme in your library. Bookshelves are displayed as customizable Slick carousels, using cover art from, and links to, your library catalog. The plugin creates a Bookshelves post type, shortcode, widget, and custom taxonomy.
