The BNC BiblioShare plugin is for book reviewers, book bloggers, library webmasters, anyone who wants to put book covers and data on their WordPress blog or website. Use the plugin button in the WordPress visual editor or insert a ‘shortcode’ with a book number in a WordPress post, page or widget. The plugin will display a book cover image, author, and other book data from BiblioShare (http://biblioshare.org). The plugin is built on the OpenBook WordPress plugin. As with OpenBook, users can control the content and styling through templates. The plugin inserts COinS to integrate with applications like Zotero. Librarians can point the plugin to their library records using an OpenURL resolver.
Requirements. To use the plugin, your server must use PHP 5 or higher, and cURL must be enabled.
